Flat and curved metal-coated mirrors

Main features

 

  • Mirror substrates fabricated from high-quality UV grade fused silica material
  • UV enhanced aluminum, protected aluminum, protected silver and protected gold metallic coatings selection
  • Relatively uniform reflectance over wide wavelength range 
  • Flat and curved (ROC from -50 mm to -200 mm) selection
  • Custom metal-coated mirrors available upon request

 

Application examples

 

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

  • Description
  • Specifications

Metal-coated mirrors exhibit relatively uniform reflectivity over wide wavelength range. They are pretty much insensetive to angle of incident and polarization state of the light. Therefore, these mirrors are preffered for broadband and white-light applications, thus their reflection losses are higher compared to dielectric thin-film mirrors.
