Robert W. ★★★★★

Replaced the old mirrors in my laser setup and the reflection stayed crisp across the visible range, just as the >97.5% spec promised. The 12.7mm Borofloat substrate feels solid enough that I don’t worry about flex when I tweak the mount.

Michael ★★★★★

Swapped these in on my beam-steering setup and the difference in alignment stability was obvious right away. The 12.7mm Borofloat substrate is thick enough that it doesn't flex in the mount, and I'm getting clean return across both my 1064nm and 1550nm paths.

Lucy Y. ★★★★★

The broadband reflectance really impressed me — I'm getting solid output from visible all the way out to the mid-IR with no drop-off. The 12.7mm Borofloat substrate also feels hefty and stable when I'm mounting it in the beam path.
