Condition: Used

This is a used Nikon Plan 10x/0.25 infinity-corrected Plan Achromat objective (part number MRL00102) with a 10.5 mm working distance. Designed for brightfield microscopy, it delivers flat-field imaging and chromatic aberration correction across the visible spectrum, making it well suited to routine laboratory, clinical, and photomicrography applications.

What is typically included:
• Nikon Plan 10x/0.25 ∞/- WD 10.5 objective

The Nikon CFI Plan Achromat 10x/0.25 (part number MRL00102) is part of Nikon's CFI60 infinity-corrected optical system — a proprietary platform combining infinity optics with the performance of Nikon's CF optical system. The 60 mm parfocal distance standard enables longer working distances while maintaining high numerical aperture, producing crisp, high-contrast, high-resolution images.

Nikon's CFI Plan Achromat series provides flat-field correction over the entire field of view and chromatic aberration correction throughout the entire visible spectrum. These objectives are suitable for routine laboratory work, clinical research, and photomicrography. The Plan Achromat correction class corrects for spherical aberration at one wavelength and chromatic aberration at two wavelengths, making it an economical yet capable choice for brightfield applications.

The objective is also widely used in extreme macro photography, capable of delivering sharp results in the 5:1–10:1 magnification range when paired with an appropriate tube lens.
