Pyranometer ML-020VM
|
ML-020VM
|
 |
- The configuration of silicon photodiode and filter is adopted
for ML-020VM Photometric sensor. This configuration makes the spectral
sensitivity of ML-020VM high. |
PRINCIPLE OF MEASUREMENT
 |
Special designed collector and diffuser are mounted on the upper part of the detector. This optical component realizes excellent character for cosine response and sensitivity. The transmitting light flux reached to the filters whose spectral response coincides for individual measuring purpose illuminance, photon number and irradiance, as shown in the following figure, the Si-photodiode detects the flux through the filters and converts accurately to electric signal proportional to the flux. |
