Did not find a test measurement that suits your needs? Non-standard test measurements are available aswell, therefore do not hesitate to contact us for more information. 

Metrology and quality assurance
  • Wavefront distortion in transmittance/reflectance for parallel and spherical optics (Verifire, Zygo)
  • Transmittance and reflectance of optical elements in 200-1700 nm wavelength range (Photon RT, EssentOptics)
  • Optical microscopy with polarized light option (Olympus)
  • Beam quality (BeamSquared, Ophir)
  • Wavelength stability for lasers with 3 pm resolution (WS6, HighFinesse)
  • Environmental temperature & humidity tests to test laser performance, coating durability, glue aging, etc. (MKF 56, Binder)
