Paper Abstract

To ensure the performance of the optical components in birefringent filter, high precision constant temperature condition is necessary. We research and realize a new thermostat for it. Firstly, we compare and select the high precision temperature sensors and designed the complicated signal acquisition circuits; Secondly, we design and assemble the high efficiency thermal insulation layers and a secondary thermostat; Thirdly, we use an ARM 7 processor as the central processing unit and realize the intelligent heat algorithm. Two sets of this new generation thermostat had been put into use since 2012, the temperature variation resolution of this new thermostat is better than 0.001°C and the temperature stability of the birefringent filter is within 0.01°C.
