Cosine Receptors

Source: StellarNet, Inc.

Cosine receptors are used to couple fiber cables and collect light with a 180o field of view through demountable diffusers. This is ideal for applications involving light/laser source characterization, UV light emission, LED color and spectral intensity, solar irradiance measurements, and other light measurement applications.

Cosine receptors can provide both relative and absolute spectral intensity measurements. StellerNet’s offerings are as follows:

  • CR2 is a ¼” diameter UV-VIS-NIR cosine receptor using a polymer diffuser for 200-1700nm & 180° FOV.

     
  • CR2-RA is a 90° right-angle Cosine Receptor cube.                         

     
  • CR2-AP is a 10% aperture for the CR2 that extends the system dynamic range by an order of magnitude, thus enabling spectral measurements of sources that are 10 times brighter.

     
  • CR-LENS is a cosine receptor lens assembly that reduces the field of view from 180 degrees to a small spot. Adjustable focus allows variable distance from target surface such as OLED displays.

     
  • CR1-UVN is a 1/2" diameter UV-VIS-NIR cosine receptor designed for use as a target surface for laser measurement. CR1-UVN can also be used as a general purpose diffuser (transmission approx 10%) for many applications.

     
  • CR2-OR is a CR2 with special O-Ring seal for underwater applications.

     
  • CR2-TP miniature tripod for mounting the CR2, CR1-UVN, or IC2.
