Chapter 7: Temperature Control 

Synapse monitors and regulates the array’s set point temperature via its thermostatic 
control circuitry. For optimum array performance with respect to dark current, quantum 
efficiency and signal-to-noise ratio, Synapse typically provides a default cooling set point 
temperature -70 

°

C (203 K). 

Array temperature setability is provided in steps of ± 0.1 

°

C resolution. From a 

temperature stability standpoint, once thermal equilibrium has been reached, the 
detector’s cooler power and thermostat control circuitry ensure that the array temperature 
will not drift more that 0.1 

°

C from the commanded value.
