Chapter 2 PIXIS-XF Camera System 17
• Fan
Air-cooled cameras contain an internal fan. Its purpose is to:
— Remove heat from the Peltier device that cools the CCD array, and
— Cool the electronics.
An internal Peltier device directly cools the cold finger on which the CCD is
mounted. The air drawn into the camera by the internal fan through the back
slots on the side panels and exhausted through the front slots on the side
panels then removes the heat produced by the Peltier device. The fan is always
in operation and air-cooling of both the Peltier and the internal electronics
takes place continuously. The fan is designed for low-vibration and does not
adversely affect the image. For the fan to function properly, free circulation
must be maintained between the sides of the camera and the laboratory
atmosphere.
• Coolant Ports
Liquid-cooled cameras have internal hoses that can be connected to the
CoolCUBE
II
circulator via the coolant ports on the side of the camera (either
port can be the input). As is the case with circulating air (see above), circulating
coolant removes the heat produced by the Peltier device. This means of heat
removal is designed for vibration-free data acquisition. For the circulating
coolant to function properly, free air circulation must be maintained between
the sides of the CoolCUBE
II
and the laboratory atmosphere.
CAUTION!
!
Use only the hoses and circulator shipped with your system.
Attaching any other hoses or circulator voids the warranty.
