• 📐 NA 0.25 / WD 10.5mm — generous working distance for comfortable slide manipulation and specimen handling
• ♾️ Infinity corrected — compatible with Olympus BX, CX, and IX series infinity optical systems
• 🔩 RMS thread — standard mount for direct nosepiece integration
• ✅ Condition: New

🔧 Product Description

The Olympus PlanC N 10X PH1 (part number N4239600) is a new infinity-corrected Plan Achromat phase contrast objective designed for the Olympus BX, CX, and IX series microscope platforms. At 10X with a numerical aperture of 0.25 and a working distance of 10.5mm, it provides the wide field of view and generous clearance that make it the ideal starting objective for phase contrast workflows — whether you're scanning a flask of cells, locating regions of interest on a slide, or monitoring live cultures over time.

Phase contrast at 10X is the workhorse configuration for cell biology and microbiology labs. The PH1 phase ring is matched to the condenser annulus for 10X objectives, converting optical path length differences in transparent specimens into visible contrast — revealing cell membranes, nuclei, organelles, and motility without any chemical intervention. The PlanC N designation indicates Plan Achromat correction, delivering a flat, sharp field from center to edge that is essential for accurate cell counting, imaging, and documentation.

The 10.5mm working distance is notably generous for a 10X objective, providing comfortable clearance for thick substrates, multi-well plates, and chamber slides. This is a brand-new objective with factory-fresh optics.

🔎 Typical Applications

• Live-cell imaging of mammalian cell cultures (adherent and suspension)
• Microbiology — bacteria, yeast, and protozoa observation
• Cell counting and confluence monitoring in tissue culture flasks
• Embryology and developmental biology
• Phase contrast setup and condenser alignment on BX, CX, and IX systems
