K9 flat mirror

  • Flat mirror, the reflecting surface is a plane, which is a mirror that can be used in a variety of applications, including beam turning, interferometry, or as an optical component in an imaging system. The important parameters of flat mirror are: surface shape and reflectivity. High surface accuracy can reduce the amount of light loss caused by dispersion.
  • Borisun optics provides mirrors without coating and with reflective film. The options of reflective film include ordinary protective aluminum film, protective ultraviolet reflective aluminum film, protective silver film and protective gold film. Fused silica substrates are suitable for UV applications.
