Non-standard test measurements

In partnership with scientific and industrial partners, we are able to offer custom metrology and quality assurance services. 

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

Metrology and quality assurance
  • Wavefront distortion measurements in transmittance/reflectance for parallel and spherical optical elements (Verifire, Zygo)
  • Transmittance and reflectance measurements of optical elements in 200 nm - 1700 nm wavelength range (Photon RT, Essent Optics)
  • Optical microscopy with polarized light option (Olympus)
  • Laser beam quality measurements (Beam Squared, Ophir)
  • Laser wavelength stability measurements with 3 pm resolution (WS6, HighFinesse)
  • Laser performance, coating durability, glue aging, etc. measurements in different environmental conditions (MKF 56, Binder)
