With a 33.5mm working distance and 2.4mm field of view (with Ø24 eyepiece), this objective is the natural starting point in a multi-magnification M Plan Apo inspection workflow: rapid wide-area survey and defect location at 10×, followed by detailed inspection at 50× or 100×. The 33.5mm working distance provides clearance for the full range of semiconductor inspection fixtures, environmental chambers, cryostats, vacuum systems, and laser processing setups, as well as ample room for beam delivery optics and collection systems. The plan apochromat correction ensures flat-field imaging with accurate chromatic registration across the full visible spectrum, essential for accurate color-based defect analysis and documentation even at low magnification. At 1.0µm resolving power, this objective delivers practical resolution for wide-area survey and navigation. For NIR or SWIR applications at 10×, see the M Plan Apo NIR 10× (378-823-15). Compatible with Mitutoyo FS series microscopes and other infinity-corrected systems with M26 thread nosepieces.

The 13mm working distance provides clearance for the full range of semiconductor inspection fixtures, environmental chambers, cryostats, vacuum systems, and laser processing setups, as well as ample room for beam delivery optics and collection systems that must coexist with the imaging objective. At 50× with a 0.48mm field of view (with Ø24 eyepiece), this objective provides a practical balance between field of view and resolution for detailed surface inspection, defect analysis, and feature measurement. The plan apochromat correction ensures flat-field imaging with accurate chromatic registration across the full visible spectrum, essential for accurate color-based defect analysis and documentation. At NA 0.55 with 0.7µm resolving power, this objective delivers sub-micron resolution for detailed inspection. For NIR or SWIR applications, see the M Plan Apo NIR 50× variants (378-825-17 for maximum WD, 378-863-5 for maximum NA).

The 6mm working distance solves one of the most challenging problems in high-magnification microscopy: how to achieve 100× magnification when the specimen cannot be brought within 0.2mm of the objective front element. This enables high-magnification inspection of specimens in environmental chambers, cryostats, vacuum systems, industrial fixtures, and laser processing setups where standard 100× objectives are physically incompatible. The plan apochromat correction ensures flat-field imaging with accurate chromatic registration across the full visible spectrum, essential for accurate defect documentation and color-based analysis at 100×. At NA 0.70 with 0.7µm resolving power, this objective delivers sub-micron resolution for the most demanding visible-light inspection applications. The dry (air) design eliminates the need for immersion media, making it practical for use in industrial and semiconductor environments. For applications requiring NIR or SWIR transmission (silicon wafer backside inspection, Raman spectroscopy, NIR laser delivery), see the M Plan Apo NIR 100× (378-826-15). Compatible with Mitutoyo FS series microscopes and other infinity-corrected systems with M26 thread nosepieces.

With a 13mm working distance — compared to 0.1–0.2mm for standard 100× objectives — this objective provides clearance for specimens in environmental chambers, cryostats, vacuum chambers, laser processing systems, and industrial fixtures where standard objectives are physically incompatible. The plan apochromat correction ensures flat-field imaging with accurate chromatic registration across the full visible spectrum, essential for accurate defect documentation and color-based analysis at 100×. The M Plan Apo series is specifically designed for semiconductor IC defect evaluation and YAG laser repair applications, where the long working distance provides the clearance needed for laser delivery optics, beam steering components, and specimen fixtures to coexist with the imaging objective.

The \"SL\" designation stands for Super Long Working Distance — at 13.0mm WD with a 100X magnification and NA of 0.55, this objective occupies a class of its own. Most 100X objectives offer working distances of 0.1–0.2mm; the M Plan Apo SL delivers 13mm of clearance, enabling non-contact inspection of deep features, recessed surfaces, tall components, and specimens that cannot tolerate close objective proximity.\u003c\/p\u003e\n\u003cp\u003eThe apochromatic correction eliminates chromatic aberration across the visible spectrum, producing sharp, color-accurate images even at the edges of the field. Infinity correction ensures compatibility with modern tube lens systems and allows optical accessories (filters, beamsplitters, polarizers) to be inserted in the infinity space without focus shift. With a resolving power of 0.5µm and focal depth of 0.9µm, this objective resolves fine surface features and defects with precision.\u003c\/p\u003e\n\u003cp\u003eThis is a brand-new objective — a significant value at this price point for a Mitutoyo M Plan Apo SL.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003e🔎 Typical Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNon-contact semiconductor and wafer inspection\u003c\/li\u003e\n\u003cli\u003eMEMS, microelectronics, and PCB defect analysis\u003c\/li\u003e\n\u003cli\u003ePrecision metrology and surface roughness measurement\u003c\/li\u003e\n\u003cli\u003eInspection of tall or recessed features on industrial components\u003c\/li\u003e\n\u003cli\u003eMachine vision and automated optical inspection (AOI) systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003e📊 Key Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e378-813-3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eMitutoyo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eM Plan Apo SL (Super Long Working Distance)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMagnification\u003c\/td\u003e\n\u003ctd\u003e100X\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumerical Aperture (NA)\u003c\/td\u003e\n\u003ctd\u003e0.55\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWorking Distance (WD)\u003c\/td\u003e\n\u003ctd\u003e13.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal Length\u003c\/td\u003e\n\u003ctd\u003e2mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolving Power\u003c\/td\u003e\n\u003ctd\u003e0.5µm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal Depth\u003c\/td\u003e\n\u003ctd\u003e0.9µm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical Correction\u003c\/td\u003e\n\u003ctd\u003eInfinity corrected, apochromat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIllumination Type\u003c\/td\u003e\n\u003ctd\u003eBrightfield (visible wavelength)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThread\u003c\/td\u003e\n\u003ctd\u003eM26\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eField of View (Ø24 eyepiece)\u003c\/td\u003e\n\u003ctd\u003eØ0.24mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReal FOV (1\/2\" chip camera)\u003c\/td\u003e\n\u003ctd\u003e0.05 x 0.06mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eJapan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003chr\u003e\n\u003cp\u003e📋 \u003cem\u003eUniversity and institutional purchase orders accepted.

The NIR designation indicates that this objective uses optical glass and anti-reflection coatings selected for high transmission across the 400–1000nm+ spectral range, enabling applications including NIR reflectance imaging of silicon wafers (which are transparent at NIR wavelengths), Raman spectroscopy with NIR excitation lasers (785nm, 830nm, 1064nm), NIR laser processing and delivery, and any imaging or spectroscopy application requiring high objective transmission in the near-infrared. The 37.5mm working distance is exceptional, providing ample clearance for specimens in environmental chambers, cryostats, vacuum systems, and laser processing setups, as well as room for beam delivery optics and other components that must coexist with the imaging objective. At 5×, this objective provides a wide field of view for rapid specimen survey and navigation — the ideal starting point in a multi-magnification NIR inspection workflow before stepping up to higher magnification M Plan Apo NIR objectives.

The 20mm working distance is exceptional for a 20× objective, providing clearance for the full range of semiconductor inspection fixtures, environmental chambers, cryostats, vacuum systems, and laser processing setups, as well as ample room for beam delivery optics and collection systems that must coexist with the imaging objective. The 1800nm upper wavelength limit enables applications that require SWIR transmission including InGaAs camera imaging, SWIR fluorescence imaging, and Raman spectroscopy with long-wavelength excitation lasers (1064nm, 1550nm). For silicon wafer inspection, the extended SWIR range enables through-silicon imaging at wavelengths where silicon is highly transparent, enabling backside inspection, subsurface defect detection, and wide-area survey of large wafer surfaces at 20× before stepping up to higher magnification for detailed inspection. At 20× with a 1.2mm field of view (with Ø24 eyepiece), this objective provides a practical balance between field of view and resolution for wide-area NIR\/SWIR survey and navigation. The plan apochromat correction ensures flat-field imaging with accurate chromatic registration across the full 480–1800nm spectral range.

The 1800nm upper wavelength limit is a significant differentiator from standard NIR objectives (typically optimized to ~1000nm), enabling applications that require SWIR transmission including InGaAs camera imaging, SWIR fluorescence imaging, and Raman spectroscopy with long-wavelength excitation lasers (1064nm, 1550nm). For silicon wafer inspection, the extended SWIR range enables through-silicon imaging at wavelengths where silicon is highly transparent, enabling backside inspection, subsurface defect detection, and through-wafer imaging of thinned substrates with exceptional clarity. The 10mm working distance provides practical clearance for the full range of semiconductor inspection fixtures, environmental chambers, cryostats, and laser processing setups. At NA 0.65 with 0.4µm resolving power, this objective delivers sub-micron resolution for detailed Raman mapping, semiconductor feature inspection, and high-magnification NIR\/SWIR imaging.

The NIR designation indicates that this objective uses optical glass and anti-reflection coatings selected for high transmission across the 400–1000nm+ spectral range. At 100×, this NIR transmission capability is particularly valuable for silicon wafer and IC inspection — silicon is transparent at NIR wavelengths, enabling through-silicon imaging of subsurface structures, backside inspection of thinned wafers, and detection of subsurface defects that are invisible in visible light. For Raman spectroscopy, the high NIR transmission at 100× enables high-spatial-resolution Raman mapping with NIR excitation lasers (785nm, 830nm, 1064nm), where the long working distance provides clearance for Raman collection optics and environmental control systems. The 6.0mm working distance is exceptional for a 100× objective, providing practical clearance for specimens in environmental chambers, cryostats, vacuum systems, and laser processing setups where standard 100× objectives are physically incompatible. The plan apochromat correction ensures flat-field imaging with accurate chromatic registration across the full visible and NIR spectrum.

The 20mm working distance provides clearance for the full range of semiconductor inspection fixtures, environmental chambers, cryostats, vacuum systems, and laser processing setups. The plan apochromat correction delivers a flat, chromatic-aberration-free image with accurate color rendering across the full visible spectrum — critical for metallographic examination where grain structure, phase identification, and surface condition are assessed by color and contrast, and for semiconductor inspection where color-based defect analysis and documentation require accurate chromatic registration. At 20× with a 1.2mm field of view (with ×24 eyepiece), this objective provides a practical balance between field coverage and resolution for intermediate-magnification inspection — the natural step between wide-area 5×\/10× survey and high-magnification 50×\/100× detail in a multi-magnification M Plan Apo workflow.

Standard long working distance objectives (including the M Plan Apo NIR series) are designed for imaging uncovered specimens; when a glass cover layer is present, it introduces spherical aberration that degrades image quality. The LCD Plan Apo NIR series is specifically corrected for this glass layer, delivering optimal optical performance when imaging through a protective cover glass or flat panel substrate. The 480–1800nm spectral range enables NIR and SWIR imaging through the cover glass, including LCD panel inspection at NIR wavelengths where certain panel defects and structures are more clearly revealed, InGaAs camera imaging, and Raman spectroscopy with NIR\/SWIR excitation lasers. The 20mm working distance provides practical clearance for large panel specimens and inspection fixtures. For uncovered specimens requiring NIR\/SWIR imaging at 20×, see the M Plan Apo NIR 20× (378-824-16).

The t0.7 designation specifies that this objective is optically corrected for a 0.7mm cover glass thickness — the industry-standard substrate thickness for LCD and flat panel display glass.

The 480–1800nm spectral range enables NIR and SWIR imaging through the panel glass, including inspection at NIR wavelengths where certain panel defects, electrode structures, and backplane features are more clearly revealed than in visible light, as well as InGaAs camera imaging and Raman spectroscopy with NIR\/SWIR excitation lasers. The 17mm working distance provides practical clearance for large panel specimens and inspection fixtures.

The 1.1mm glass thickness is found in older LCD panel generations, certain semiconductor packaging substrates, and other flat panel or encapsulated specimen configurations. Selecting the correct t-value is critical: using a t0.7-corrected objective on a 1.1mm substrate (or vice versa) will introduce residual spherical aberration that degrades resolution and contrast at 50×. The t1.1 correction ensures optimal optical performance specifically for this substrate thickness. The 480–1800nm spectral range enables NIR and SWIR imaging through the 1.1mm glass layer, including inspection at NIR wavelengths where panel defects, electrode structures, and backplane features are more clearly revealed than in visible light, as well as InGaAs camera imaging and Raman spectroscopy with NIR\/SWIR excitation lasers. The 17mm working distance provides practical clearance for large panel specimens and inspection fixtures. For 0.7mm glass substrates at 50×, see the LCD Plan Apo NIR 50× t0.7 (378-829-16). For uncovered specimens at 50× NIR\/SWIR, see the M Plan Apo NIR 50× series (378-825-17 or 378-863-5 HR).
