Page 17: Optimization Of Temperature Control
3. The transient response after setting a new temperature is limited since the heat transport in the copper block is relatively slow. Furthermore, the sensor must settle to the laser temperature - it also has a non-negligible thermal capacity. Possible optimization: careful adjustment of PID parameters © 2016 Thorlabs... -
Page 18: Pid Adjustment
· Change the set temperature repeatedly between 18 °C and 22 °C . · Increase the I-share gradually. Higher values will accelerate the settling to the set temperature. The I-share is set correctly when the actual temperature reaches the set temperature in shortest time without overshoots. © 2016 Thorlabs... -
