Customer Reviews (4.6 / 5 · 5 reviews)

Violet ★★★★★

We needed a clean reference for our interferometer setup, and this sphere’s 1/20 wave accuracy immediately reduced fringing artifacts we’d been chasing for months. The 6" aperture is exactly what we needed for large optics, and for the price, it’s a solid upgrade from the generic ones we’d tried.

Ava O. ★★★★★

Swapped this in for our old F/3.5 sphere and the fringe quality on our 6-inch flats was noticeably cleaner right away. The 1/20 wave surface really shows in how little retrace error we're chasing during alignment now. Setup took a bit of care but that's the nature of the accessory.

Carter S. ★★★★★

Swapped this 6" F/3.5 sphere into our interferometer setup and the fringe contrast cleaned up noticeably compared to our old reference. The 1/20 wave rating holds up, we're seeing consistent PVr readings across multiple runs now. Worth the money if you're doing serious surface metrology.
