CL2_IR Infrared Spectral Distribution Standard (1-20µm)

  • CL2_IR SiN spectral distribution reference standard 1-20µm

Including a 40W silicon nitride emitter operating at 1250K and high emissivity the CL2_IR is an excellent source in the infrared.

A mounting bracket provides a universal interface with all optical tables and mounting systems with the calibration distance measured from a simple datum face to the rear of the lamp.
