Optoelectronic Systems Characterisation laboratory has 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).
