Our expertise has traditionally been in fiber optic test & calibration. Recently, we have acquired equipment and expertise to traceably calibrate free-space beam test equipment. Power calibration using free space beams can be typcially more accurate that when using fiber optic beams.
- For free space light source calibration, the light beam should be not more than 3 mm diameter in order to fit onto a 5mm detector
- For free space power meter calibration, the detector diameter should be 3 mm or larger
- For free space attenuator calibration, the device should accommodate a light beam 3 mm diameter
