Optical MirrorsOur custom mirrors are carefully designed to minimize glare and offer enhanced contrast. They include the following features:

  • Full range of shapes and sizes
  • Enhanced spectrum
  • High reflectivity for a wide spectral range
  • Low polarizing (10000:1)
  • Specialty reflective coatings available: multi-layer, enhanced aluminum, protected silver, gold and dielectric
