Measurement of reflection and transmission

opsira’s metrology laboratories can also measure the spectral characteristics of surfaces and materials. We have the ability to measure the spectral reflection or transmission, specular or diffuse, within wavelength ranges from 200nm to 1100nm.

Possible measurements:

  • Measurement of the diffuse as well as specular reflection and transmission
  • Angle-depending measurement of the spectral characteristics (e.g. regarding thin-film coatings)
  • Color comparisons
  • Measurement of the photometrically weighted reflection and transmission (in consideration of the light source spectrum)
