If you’ve spent any time working with Olympus WH10x/22 eyepieces, you’ve probably run into this frustrating issue: the plastic retention ring that holds the eyecup in place cracks over time. It’s not your fault—it’s just the nature of aging plastic. With years of use and exposure, the factory plastic ring tends to become brittle and eventually fails, leaving your eyepiece without its essential support.

At Munday Scientific and Microscope Marketplace, we understand how annoying (and expensive) that can be. With basic replacement eyepieces often costing upwards of $300, tossing a perfectly good WH10x eyepiece because of one broken part just doesn’t sit right with us.

That’s why we developed a simple and cost-effective solution:
Our aluminum retention ring is designed to replace the broken plastic one, threading directly onto your existing WH10x eyepiece. It restores full functionality and stability to the eyepiece without the need to purchase a full replacement.

Key Benefits:

Precision-machined aluminum for durability and long-term reliability

Threads onto your original WH10x eyepiece housing—no glue or jury-rigging needed

Lets you retain your high-quality optics without overspending

Easy to install—just watch our step-by-step guide on YouTube here

Whether you're maintaining a fleet of microscopes or just trying to get the most life out of your lab gear, this retention ring is a smart fix for a common failure.
