• What It’s Good For / Typical Applications

  • High-reflectance mirror in the visible to near-IR range, due to very good silver reflectivity.

  • Applications with pulsed lasers, since it has specified damage thresholds.

  • Optical setups where a compact, high-quality planar mirror is needed (e.g., in beam steering, alignment, etc.).
