I was skeptical about the reflection quality in the infrared range, but these mirrors easily handle my CO2 laser setup with no noticeable loss. The 25.4mm size fits perfectly into my existing mounts.

Bought the 25.4mm protected silver mirror to bounce a 1064nm beam around my setup, and the reflectivity is holding steady even after a few months of daily use. The silver coating hasn't tarnished at all, which was my main worry with bare silver. Surface flatness looks great under my interferometer t
