Alkor Technologies - manufacturer of Dielectric mirrors for narrowband or broadband applications covering visible and IR spectrum. We offer wide selection of plane and spherical dilectric mirrors for most popular laser lines.
A dielectric mirror is a type of mirror composed of multiple thin layers of dielectric material, typically deposited on a substrate of glass or Fused Silica. By careful choice of the type and thickness of the dielectric layers, one can design an optical coating with specified reflectivity at different wavelengths of light.
Dielectric mirrors are also used to produce ultra-high reflectivity mirrors: values of 99.5% or better(typical for metals does not exceed 95-98%) over a narrow range of wavelengths can be produced using special techniques. Alternatively, mirrors can be made to reflect a broad spectrum of light. Radiation resistance is several Joules per cm2 (vs. 0.3 J/cm2 for metals). These coatings are usually designed for a 0 or 45 degree angle of incidence. Usually substrate of the mirror is N-BK7 or Fused Silica. We can use CaF2, Sapphire or another substrates by your request.
