Penelope N. ★★★★★

I was nervous about compatibility, but this 3-inch f/2.0 sphere fit perfectly into my existing mount. The surface quality is visibly flawless under test, giving me clean, repeatable interferograms for my mid-wave infrared setup.

David ★★★★★

Been hunting for a clean 3-inch sphere for our 3.39 μm setup for a while, and this one dropped right in with no realignment headaches. Fringes look tight and stable across the full aperture, way better than the older optic it replaced.

Zoe W. ★★★★★

Snapped this into our interferometer for a 3.39 μm setup and the fringe contrast was clean right out of the case. The 1/20th wave rating at that wavelength isn't marketing fluff — our test data backs it up. Mounting was straightforward too.
