4.8 QCL temperature controller(TCU151)
4.8.1 Description
The TCU151 is used to control the laser’s temper-
ature inside the Laboratory Laser Housing.
It uses a PT100 sensor to measure the tempera-
ture of the cold plate and maintains a pre-set tem-
perature either from a front panel knob or from a
user supplied voltage.
