Penelope ★★★★★

Pulled it out of the box and the 4% reflectivity is exactly what I needed for my interferometer setup. The surface quality is visibly flawless.

Ellie ★★★★★

The lambda/25 PVr spec is spot on—my interferometry checks came out clean with no measurable surface error. The 4% reflectivity also made alignment a breeze, even with the 12-inch diameter.

Olivia U. ★★★★★

I needed a reference surface for checking my interferometer setup, and the lambda/25 PVr spec on this 12-inch flat is no joke. Fringes came out clean and evenly spaced across the whole aperture, which I honestly wasn't expecting at this price.
