Fura-2 requires excitation at 340nm and 380nm, with the ratio of emission intensities used to calculate intracellular calcium concentration. Standard oil immersion objectives have significantly reduced transmission below 380nm, making them unsuitable for accurate fura-2 ratiometric imaging. The HC PL APO UV designation indicates that this objective maintains high transmission at 340nm, ensuring sufficient UV excitation intensity for accurate ratiometric calcium measurements. The plan apochromat correction ensures accurate chromatic registration across all fluorescence channels — essential for multi-color imaging combining UV-excited calcium indicators with visible fluorophores for simultaneous structural and functional imaging. At NA 1.30 with oil immersion, this objective provides excellent fluorescence light collection efficiency, critical for UV fluorescence applications where the photon budget is inherently limited.

Glycerol immersion (n≈1.45) sits between water (n=1.33) and oil (n=1.515) and closely matches the refractive index of living cells and biological tissues (~1.38–1.46), dramatically reducing spherical aberration when imaging deep into living specimens — maintaining image quality and resolution at depths where water immersion objectives suffer increasing aberration and oil immersion is incompatible with aqueous specimens. The HCX PL APO correction delivers Leica’s highest level of chromatic and spherical aberration correction, ensuring accurate co-localization across all fluorescence channels. At 63× with NA 1.30, this objective provides high-resolution single-cell and subcellular imaging with excellent fluorescence light collection.

Water immersion (n=1.33) eliminates the refractive index mismatch between the objective and aqueous biological specimens, reducing spherical aberration and maintaining image quality when imaging into living cells and tissues. The correction collar (0.14–0.18mm) allows fine adjustment for different coverslip thicknesses, ensuring optimal spherical aberration correction regardless of the coverslip used — a significant advantage over fixed-correction water immersion objectives, particularly in labs that use different coverslip types or image through varying thicknesses of media. The plan apochromat correction delivers Leica’s highest level of chromatic and spherical aberration correction, ensuring accurate co-localization across all fluorescence channels. At 63× with NA 1.20, this objective provides high-resolution single-cell and subcellular imaging with excellent fluorescence light collection.

color: rgb(0,0,0);\"\u003eThe Nikon CFI Plan Apo Lambda D 40× is part of Nikon’s Lambda D objective series — a line specifically engineered for the demands of modern digital microscopy. The Lambda D designation indicates optimization for reduced focus shift across wavelengths, ensuring that fluorescence channels remain parfocal when switching between excitation wavelengths — a critical requirement for multi-color widefield and confocal imaging where z-drift between channels would compromise co-localization accuracy and 3D reconstruction quality. At NA 0.95, this is the highest NA available in a dry 40× objective, providing resolution and light collection approaching that of lower-NA immersion objectives without the need for immersion media — making it ideal for high-throughput screening, slide scanning, and any workflow where the convenience of a dry objective is preferred without sacrificing optical performance. The plan apochromat correction ensures accurate chromatic registration across all fluorescence channels. Compatible with Nikon CFI series microscopes including Eclipse Ti2, Ti, Ni, E, and FN series.

The APO (apochromat) correction delivers the most accurate chromatic aberration correction available, ensuring that fluorescence signals from multiple channels are precisely co-registered — critical for co-localization studies, FRET experiments, and any multi-color imaging workflow where chromatic shift between channels would compromise data integrity. The Lambda S designation indicates optimization for reduced focus shift across wavelengths, making this objective particularly well-suited for multi-color confocal, structured illumination (SIM), and TIRF microscopy where maintaining parfocality across channels is essential. The long working distance (LWD) of 0.61mm provides more clearance than standard 40× water immersion objectives, accommodating thicker coverslips, imaging chambers, and experimental setups where additional working room is needed. Water immersion (n=1.33) eliminates the refractive index mismatch between the objective and aqueous biological specimens, reducing spherical aberration and maintaining image quality when imaging into living cells and tissues.

The Super Fluor designation indicates superior UV transmission down to 340nm — the excitation wavelength of fura-2 and indo-1, the most widely used ratiometric calcium indicators. Standard oil immersion objectives have significantly reduced transmission below 380nm, making them unsuitable for accurate fura-2 ratiometric imaging where the 340nm excitation beam must reach the specimen with sufficient intensity for accurate ratiometric calcium measurements. The CFI Super Fluor series addresses this by using optical glass with high UV transmission, ensuring reliable performance at 340nm and below. Beyond calcium imaging, the high UV transmission also enables efficient photo-activation of caged compounds — caged ATP, caged calcium, caged neurotransmitters, and other UV-activated probes used in cell physiology and optogenetics research — where the efficiency of photo-uncaging depends directly on the UV transmission of the objective. At NA 1.30 with oil immersion, this objective provides excellent fluorescence light collection efficiency, critical for UV fluorescence applications where the photon budget is inherently limited.

This multi-immersion capability eliminates the need to swap objectives when changing between specimen types or imaging conditions: oil immersion for maximum NA on fixed specimens, water immersion for live-cell imaging in aqueous media, glycerin for refractive index matching to biological tissue, and silicone for deep tissue imaging where silicone’s refractive index (n=1.40) closely matches biological cytoplasm (~1.38). The correction collar allows fine adjustment of spherical aberration correction for each immersion medium, ensuring optimal image quality regardless of the immersion type used. The Plan Fluor fluorite design provides excellent chromatic correction and high UV-visible transmission for multi-channel fluorescence imaging. At 20× with NA 0.75, this objective provides a wide field of view for imaging large specimens, organoids, tissue sections, and multi-cell preparations across all immersion conditions.

Fura-2 requires excitation at two UV wavelengths (340nm and 380nm) with the ratio of emission intensities used to calculate intracellular calcium concentration. This ratiometric approach demands an objective with high, consistent UV transmission at both excitation wavelengths, and the UApo N 340 is specifically optimized to deliver this performance. Standard fluorite and apochromat objectives designed for visible light imaging have significantly reduced transmission below 380nm, making them unsuitable for fura-2 ratiometric imaging where accurate 340nm excitation is essential. The UApo N 340 series addresses this by using optical glass with high UV transmission, ensuring that the 340nm excitation beam reaches the specimen with sufficient intensity for accurate ratiometric calcium measurements. At NA 1.35 with oil immersion, this objective also provides excellent fluorescence light collection efficiency — critical for UV fluorescence applications where the photon budget is inherently limited by UV excitation intensity and fluorophore brightness.

Standard water immersion objectives (n=1.33) and oil immersion objectives (n=1.515) both suffer from increasing spherical aberration as imaging depth increases in biological specimens, because the refractive index of biological cytoplasm and tissue (~1.38) falls between the two. Silicone immersion oil (n=1.40) closely matches this biological refractive index, dramatically reducing spherical aberration at depth and maintaining image quality and resolution throughout thick specimens — making the UPlanSApo 30× Silicone the preferred choice for deep confocal imaging, 3D reconstruction of thick tissue sections, and long-term live-cell imaging where maintaining optical performance at depth is critical. The super apochromat correction ensures accurate chromatic registration across all fluorescence channels, essential for multi-color co-localization studies.

The super apochromat correction compensates for both spherical and chromatic aberrations to the highest degree available in the Olympus objective range, ensuring accurate co-localization across all fluorescence channels and precise chromatic registration from the UV-visible through near-infrared — essential for multi-color TIRF, PALM, STORM, and structured illumination microscopy where chromatic accuracy directly impacts localization precision and co-localization fidelity. At NA 1.35, this objective delivers the high light collection efficiency required for single-molecule detection and TIRF imaging, where maximizing photon collection from the evanescent field is critical for signal-to-noise ratio. The 60× magnification provides the ideal combination of high magnification and field of view for single-cell and subcellular imaging on Olympus systems.

At NA 1.30, this objective provides the maximum light collection and resolution available in the Olympus silicone lineup, making it the definitive choice for the most demanding fluorescence and confocal imaging applications where both optical performance at depth and chromatic accuracy are critical. Silicone immersion oil (n=1.40) closely matches the refractive index of biological cytoplasm and tissue (~1.38), dramatically reducing spherical aberration when imaging deep into living cells, organoids, brain slices, and thick tissue sections — maintaining image quality and resolution at depths where water immersion objectives suffer significant aberration. The super apochromat correction ensures precise chromatic registration across all fluorescence channels, essential for multi-color co-localization, FRET, and any imaging workflow where chromatic shift between channels would compromise data integrity.

The EC designation indicates that this objective has been optimized to reduce internal reflections and stray light compared to standard Plan-Neofluar objectives, resulting in visibly improved contrast in brightfield, darkfield, phase contrast, DIC, fluorescence, and polarization imaging. At 100×, this enhanced contrast performance is particularly valuable for subcellular imaging where fine structural details — organelle boundaries, cytoskeletal elements, membrane dynamics — require maximum contrast to be clearly resolved. The EC Plan-Neofluar series is especially well-suited for labs that use multiple contrast techniques on the same specimens, as a single objective delivers optimized performance across all modalities without compromise. At NA 1.30 with oil immersion, this objective provides excellent resolution and fluorescence light collection for the most demanding subcellular imaging applications. The Plan-Neofluar fluorite elements provide excellent chromatic correction and UV-visible transmission for multi-channel fluorescence imaging.

The correction collar (0.13–0.21mm) allows the objective to be optimized for different coverslip thicknesses — from standard #1 (0.13mm) through #1.5 (0.17mm, the most common) to #2 (0.21mm) — ensuring optimal spherical aberration correction regardless of the coverslip used. This makes the objective significantly more versatile than fixed-correction dry objectives, particularly valuable in labs that use different coverslip types across different specimen preparations. The plan apochromat correction delivers Zeiss’s highest level of chromatic and spherical aberration correction, ensuring accurate co-localization across all fluorescence channels and sharp, flat-field imaging in brightfield and DIC. At NA 0.95, this objective provides resolution approaching that of lower-NA immersion objectives without the need for immersion media — ideal for high-throughput screening, slide scanning, and workflows where the convenience of a dry objective is preferred.

At 63× with NA 1.40, this objective provides the ideal combination of high magnification and maximum oil immersion NA for single-cell and subcellular imaging, delivering the resolution and fluorescence light collection required for the most demanding imaging applications. The plan apochromat correction ensures accurate chromatic registration across all fluorescence channels, essential for multi-color co-localization, FRET, and any imaging workflow where chromatic shift between channels would compromise data integrity. The 63× magnification is the preferred choice for many researchers on Zeiss systems, providing a slightly larger field of view at equivalent NA compared to 60× objectives.

The 2.2mm working distance provides ample clearance for the full range of standard tissue culture vessels, enabling high-magnification fluorescence and brightfield imaging of living cells in standard culture conditions without the need to transfer cells to specialized coverslip-bottom dishes. This is the standard (non-phase-contrast) version of the LD Plan-Neofluar 63× — catalog number 421380 — suitable for fluorescence, DIC, and brightfield imaging workflows that do not require phase contrast. The Plan-Neofluar fluorite design provides excellent chromatic correction and high fluorescence transmission for multi-channel imaging across the visible spectrum.

The correction collar (KORR) allows fine adjustment for different coverslip thicknesses, ensuring optimal spherical aberration correction regardless of the coverslip used — a significant advantage over fixed-correction dry objectives, particularly valuable in labs that use different coverslip types across different specimen preparations. At NA 0.95, this objective provides resolution approaching that of lower-NA immersion objectives without the need for immersion media — ideal for high-throughput screening, slide scanning, and workflows where the convenience of a dry objective is preferred at 63×. The Plan-Neofluar fluorite elements provide excellent UV-visible transmission for fluorescence imaging alongside high-contrast brightfield and DIC performance.

Standard objectives are optimized for room temperature (typically 23°C); as temperature rises to 37°C for live-cell imaging, the refractive indices of immersion media and biological specimens shift, introducing spherical aberration that degrades image quality. The Plan-Neofluar 25×\/0.80 is designed to maintain optimal optical performance across this temperature range, making it the correct choice for live-cell imaging workflows where image quality at physiological temperature is critical. The multi-immersion design supports oil (n=1.515), water (n=1.333), and glycerin (n≈1.45) — with water immersion being particularly well-suited for live-cell imaging at 37°C, where the refractive index of water closely matches that of aqueous biological specimens and minimizes spherical aberration.

The 25× magnification with FN 26.5 provides a wide imaging field ideal for organoids, brain slices, embryos, and other large specimens where both field coverage and optical performance at depth are required. The 2.0mm working distance is exceptional for a silicone immersion objective at NA 0.85 — providing ample clearance for thick specimens, imaging chambers, and experimental manipulations beneath the objective. Silicone immersion (n=1.40) closely matches the refractive index of biological cytoplasm and tissue (~1.38), reducing spherical aberration when imaging deep into living specimens and maintaining image quality at depths where water immersion objectives suffer increasing aberration. The super apochromat (PLANAPO) correction ensures accurate chromatic registration across all fluorescence channels, essential for multi-color co-localization and any imaging workflow where chromatic shift between channels would compromise data integrity. Compatible with Olympus BX and IX series microscopes.
