Hannah ★★★★★

The 90% reflectivity is perfect for my interferometry bench work, and the 1/20 wave flatness held up beautifully across repeated checks. Arrived clean, well-packaged, and it's been dead stable in my setup.

Richard ★★★★★

I needed a reliable reference flat for interferometry work, and this 1/20 wave surface delivers the precision I was hoping for. The 90% reflectivity pair perfectly with my setup.

Grace ★★★★★

The 90% reflectivity gives me nice bright fringes in my interferometer setup, way easier to align than my old flat. Surface looks flawless under the eye and the 6" size fits my mount perfectly.
