EOP Optical Probe


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.

Features

  • flexible optical fiber connector
  • multiple probes with different cosine correction and light throughput
  • special probe with specified field-of-view of 5.7 degrees
