Optoelectronic Systems Characterisation Laboratory

Optoelectronic Systems Characterisation laboratory implemented the LST EN ISO/IEC 17025:2018 standard requirements for the competence to carry out tests using standard and non-standard methods.

Visible and IR range cameras testing

Measurements are performed using an optical projector, which projects an optical field with an extremely uniform distribution. The optical field is created using an optical imaging system with an absolutely black body source or a VIS/SWIR integrating sphere source. Optical radiation sources are calibrated using a standard available from the National Institute of Standards and Technology (NIST).

Laser power measurement

  • Calibrated optical power from 40 μW to 3 W and single shot energy from 20 μJ to 2 J, measurements wavelength range from 0.19 μm to 11 μm.
  • Calibrated power of very low level CW or quasi CW sources measurement in optical power range < 100 nW to 100 mW over a broad spectral range from 0.15 µm to 12 µm.
