Customer Reviews (4.6 / 5 · 5 reviews)

Zoe ★★★★★

The enhanced aluminum coating handles my 532nm laser perfectly, with zero ghosting even at steep angles. The fused silica substrate polished to 1/10 wave makes alignment a breeze.

Evelyn ★★★★★

I swapped out my old mirror for this fused silica one and the beam alignment barely needed touching up. Surface quality is clean with no visible scatter, and it's been holding up fine in my setup for a few weeks now.

Sophia F. ★★★★★

The broad 450-2000nm reflectivity is spot on, and the fused silica body feels noticeably sturdier than my old glass mirrors. Polished edge is clean, no chips out of the box. Exactly what my setup needed.
