Daniel ★★★★★

I set this flat up for an interferometric test and the lambda/15 surface figure gave me rock-solid null fringes on the first try. The 4% reflectivity is exactly what I needed for my coated reference setup.

James ★★★★★

The 4% reflectivity is spot on for my interferometry setup—no stray fringes muddying the data. Surface figure held up perfectly across the full 12 inches, and the PVr spec feels reassuringly tight for the price.

Avery T. ★★★★★

The lambda/15 surface figure on this flat is genuinely impressive once you throw it in an interferometer—nice clean fringes across the whole 12-inch aperture. The 4% reflectivity coating also cuts down on those annoying ghost reflections I kept fighting with my old reference.
