Structure

The laboratory performs: 

• Continues wave collimated laser beam (beam diameter up to  6 mm) calibrated average power measurements. Measurements are performed in the spectral range of 0.19 µm - 11 µm and in the average power range of 40 µW - 3 W. 

• High-end bench to test visible and IR cameras

Measurements are performed using the HGH Inrared Systems, IRCOL300 / 1500 system, 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 and a VIS / SWIR integrating sphere source. Optical radiation sources (absolute black body source, VIS / SWIR integrating sphere source) are calibrated using a standard available from the National Institute of Standards and Technology (NIST).
