Abstract:

The working principles of the optical glass the ECT light source temperature controller (hereinafter referred to as the thermostat) are introduced.With regard to the special requirements for light source intensity output and its center wavelength stability of optical glass ECT,the superimposed pulse fine adjustment of the light source based on high-power voltage regulator temperature control is proposed.The hardware circuit is given.The test results show that the optical glass the ECT light source temperature can be controlled at +25 ± 0.1 ℃ within the range of -40 ℃~+70 ℃,which proves the feasibility of the temperature control.

Key words: optical glass the ECT;temperature controller;current transformer
