HR mirror R 99.9 percent for He-Ne ruby and red diode lasers 600-750 nm Dielectric high-reflectivity mirror coating detail for visible red laser optics 25 mm BK7 HR mirror side view, 5 mm thick flat optical substrate

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
  • Suitable for He-Ne, ruby and visible red diode laser optics
  • Useful in optical resonators, beam steering and precision alignment setups
  • 25 mm diameter, 5 mm thick BK7 optical substrate
