Super-polished substrates

Main features

 

  • Fabricated from high-quality UVFS glass
  • Laser grade polished front side, fine ground back side
  • <1 Å or <2 Å roughness options
  • Dielectric thin-film or metallic coatings deposition service on demand

 

Application examples

 

  • Ideal for ultrafast applications due to ultra-low scatter
  • End mirrors in CEAS (Cavity-enhanced absorption spectroscopy) instruments
  • Mirrors in RLG (ring laser gyroscope) devices used in navigational systems for aircraft and spacecraft
  • Cavity mirrors in green (543 nm) HeNe lasers

  • Specifications

Super-polished UVFS substrates with remarkable surface rougness and flatness properties are designed to be coated with dielectric thin-film or metallic coatings and used as mirrors for high-precision, high-power and ultrafast applications. By using super-polished subansgstrom surface roughness optics light scattering effects are minimized and overall system efficiency is increased.
