Solutions
QRAD provides instrumentation solutions for test and calibration in the field of photometry and radiometry based on the technologies transferred from KRISS.
- Single Photon Metrology
-
Measurements of optical detector properties such as spectral responsivity, non-linearity, dynamic range, sensitivity, and spatial/angular/temporal response characteristics can be realized with high accuracy and reliability.
