5. CAMERA & CHILLER SETUP
This section discusses setting up the camera for operation, including connecting the coolant
pipes, along with a description of all feedthrough parts. The use of liquid cooling is also
discussed, as well as stating important precautions when using the camera.
5.1 Liquid Cooling
This section discusses setting up the liquid cooling, as well as using the Thermotek chiller, if
purchased from Raptor.
Liquid cooling must be used when using the TEC. This is needed to dissipate heat
away from the hot side of the TEC. Do not enable the TEC if liquid cooling is not being
used, otherwise damage to the camera will occur.
5.1.1 Liquid Cooling Connection to the Camera Head
The camera electronics drive a ThermoElectric Cooler (TEC) to cool the CCD. The hotside
of the TEC MUST be cooled via circulating coolant. Connection to the coolant channel is
made via two Swagelok compression fittings, suitable for connection to ¼” O.D. coolant
pipes, as shown in Figure 5.
Please ensure compatibility with these connectors on the camera module before attempting
to connect the coolant supply. Also ensure the coolant connections are completely leak tight
before pumping the vacuum system down and circulating coolant. The TEC within the
camera must not be switched on without coolant circulating through the camera otherwise
permanent damage may occur.
Ensure ferrule set is in place and pipe is
seated correctly in fitting before
tightening.
