Photo-Detector Characterization System:

We provide system solution to characterize the spectral response and  sensitivity of photo-detectors.

1. Current Meter 2. Device under Test 3. Integrating Sphere
4. Monochromator 5. Personal                  Computer 6. Power Supply
7. Silicon Detector 8. V(£f) Detector

9. 1/2 Axis Stepping Motor
10. Stepping Motor Controller 11. Light Box 12. Iris

1. Photo detector spectral response  characterization schematic:

Power supply lights up the bulb in the light box, the spectral components of halogen bulb are separated by monochromator and collected by the photo-detector-under-test. Then, the photo current read by current meter will be collected and processed by personal computer.
