Instrument Systems provides a range of optical probes for measuring irradiance and illuminance, and also for general coupling of light into the spectrometer. These probes differ in the degree o f light throughout, the spectral range and cosine correction. All models of optical probes offered by Instrument Systems include a diffuser for the incident light. The entrance for the optical fiber used to couple the light into the spectrometer is located directly behind this diffuser.
