Ava S. ★★★★★

The f/0.65 focal ratio makes alignment with my interferometer setup surprisingly straightforward, and the 1/20 wave accuracy shows up clearly in my test data. Shipping was quick and the packaging kept the optics pristine.

Alexander ★★★★★

The wavefront error spec of 1/20 wave really shows up in the data—my interferograms came out cleaner than with the older optics I was using. It’s a solid, hefty piece that feels built to last, and the f/0.65 is just right for my setup.

Zoe ★★★★★

I was nervous about the f/0.65 aperture, but the wavefront accuracy held up perfectly across the full 4-inch clear span. The 1/20 wave spec is real—my test plate readings were clean and repeatable without any edge roll-off. Definitely worth the wait for this level of consistency.
