Flat and curved metal-coated mirrors

Main features

 

  • Mirrors substrates fabricated from high-quality UV grade fused silica
  • Standard substrates dimensions are ⌀25,4x5 mm
  • UV enhanced aluminum, protected aluminum, protected silver and protected gold metallic coatings selection
  • Relatively uniform reflectance over wide wavelength range
  • Radius of curvature selection from infinity to -200 mm
  • Custom metal-coated mirrors available upon request

 

Application examples

 

  • Broadband reflectivity and low chromatic dispersion mirrors for whitelight interferometers and broadband laser sources
  • Partially transmissive broadband mirrors
  • Extremely long infrared (up to 20 μm) mirrors

  • Description
  • Standard specifications

Metal-coated mirrors exhibit relatively uniform reflectivity over wide wavelength range. They are nearly insensetive to angle of incidence and polarization state of light, thus their reflection losses are significantly higher compared to dielectric thin-film mirrors.
