Olympus WH10x-H Adjustable Eyepiece

The Olympus WH10X-H is the standard adjustable widefield eyepiece for Olympus BX and IX series research microscopes, providing 10x magnification with a field number of 22 and a built-in diopter adjustment ring. The diopter adjustment allows each microscope operator to fine-tune the focus of the eyepiece independently, compensating for differences in vision between the user’s two eyes or between different users sharing the same instrument — a critical feature for binocular observation heads where both eyepieces must be individually focused for comfortable, strain-free viewing. The 30mm barrel diameter is the standard for Olympus BX and IX series observation heads, and the WH10X-H is the most commonly specified eyepiece for these platforms. As a genuine Olympus OEM eyepiece (part no. 2-U100H2) manufactured in Japan and supplied in excellent condition with flawless optics, it is a reliable replacement or spare for any BX or IX series system.
