John U. ★★★★★

The surface quality is exactly what I needed for aligning a 355nm beam—the 25.4mm fused silica substrate feels solid and the UV coating holds up nicely after weeks of use. Reflectivity above 90% across that range checks out in my setup, and polishing is visibly flawless under a loupe.

Robert E. ★★★★★

I've been running these in a UV fluorescence setup and the reflectivity below 300nm holds up way better than the bare aluminum mirrors I was using before. The 50.8mm fused silica substrate is dead flat, no visible distortion when I check it against a straightedge.

Natalie ★★★★★

Picked up the 25.4mm version for a DIY spectrometer build and the reflectivity down at 250nm is genuinely impressive, way better than the cheaper mirror I was using before. Surface is dead flat with no visible scatter under my laser.
