Temperature controlled filter / wavelength reference

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 at http://sfo.nwg.cz

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