Flat and curved metal-coated mirrors

Main features

 

  • Mirror substrates fabricated from high-quality UV grade fused silica
  • Standard substrate dimensions are ø25,4 x 5 mm
  • UV enhanced aluminum, protected aluminum, protected silver, low GDD enhanced silver, and protected gold metallic coatings selection
  • Relatively uniform reflectance over a wide wavelength range 
  • The 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 white-light interferometers and broadband laser sources
  • Partially transmissive broadband mirrors
  • Extremely long infrared (up to 20 μm) mirrors
  • Plano-convex and plano-concave designs

  • Curves
  • Standard specifications

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