Passive wavelength reference / temperature controlled filter

Thermo FBG is a high-accurate optical filter based on temperature controlled Fiber Bragg Grating (FBG). Thanks to precise electronic control it could be also used as wavelength reference with absolute accuracy of ±1 pm. Central wavelength and other optical parameters are given by used FBG. You can choose the FBGs here.

NEW: We can also offer version with implemented 3-port or 4-port optical circulator for optical power up to 1000 mW.

Key features:

  • Fine tune and high accurate optical filter
  • Wavelength reference
