Product Description
Professional high-reflectivity HR mirror with a broadband dielectric coating optimized for the 600–750 nm spectral range. This makes it useful for several visible red laser sources, including He-Ne lasers at 632.8 nm, ruby lasers at 694 nm and red diode laser optical setups.
The mirror is fabricated on a Schott BK7 optical glass substrate, with a flat/plano geometry and an optically polished second face. It can be used as a cavity high reflector, beam-folding mirror, alignment mirror or general laboratory high-reflectivity optic in the red spectral region.
- Broadband dielectric HR coating for 600–750 nm
