🔧 Product Description

The Olympus NCWHK 10x eyepiece is a widefield, high-eyepoint eyepiece designed for Olympus microscopes equipped with the standard 23mm eyetube diameter — the format used on many classic Olympus upright and inverted microscope platforms including the CH, BH, CK, and related series. The “HK” designation indicates a high-eyepoint design, which positions the exit pupil further from the eye lens than standard eyepieces, allowing users who wear eyeglasses to observe the full field of view without removing their glasses. This is a significant ergonomic advantage in clinical, pathology, and teaching environments where multiple users share a microscope. The widefield design provides a comfortable, well-corrected field of view for routine observation. As a genuine Olympus OEM eyepiece (catalog no. 2-LC510) manufactured in Japan and supplied in excellent condition with flawless optics, it is a reliable replacement for any compatible Olympus 23mm eyetube system.

🔎 Typical Applications
