We calibrate
- optical radiometers (radiance and irradiance),
- incandescent lamps (irradiance),
- optical filters (transmittance).
Scroll down for details.
We characterise the optical radiometers for:
- non-linearity,
- angular response,
- thermal sensitivity,
- polarisation effects,
- inherent straylight effects
