          介質高反鏡

          Dielectric (HR) Mirrors have the advantage of high reflectance and superior surface quality and accuracy. They offer near total reflection, minimizing losses in nearly all optical systems. These coatings are very durable, easily cleaned, and resistant to laser damage and reflectance can be more than 99%. The wavelength (range) of reflectance depends on incident angles (0 degree or 45 degree).
