IMAGE SENSOR
CCD multichannel detector head
C7973
Designed for back-thinned CCD area image sensor
C7973 is a high sensitivity multichannel detector head for use with back-thinned FFT-CCD area image sensors (S7963, S7964, S7965) that offer
high UV sensitivity and quantum efficiency. C7973 incorporates a low-noise driver/amplifier circuit that provides reliable operation from simple
external signals. C7973 includes a highly stable temperature controller that cools the sensor to a preset temperature level (Ts= -10 ˚C) as soon as
the power is turned on. If the cooler fails and causes internal circuitry to overheat, the built-in protection circuit automatically turns off the power to
the thermoelectric cooler. Despite its compact size, the housing configuration is designed for good heat dissipation, and threaded mounting holes
on the front panel allow connections to other devices such as monochrometers.

*1: In normal CCD image sensors that receive light from the front surface, the active area is covered with electrodes for charge transfer.
These electrodes cut off UV radiation incident on the image sensor and also reduce the quantum efficiency. In contrast, back-
thinned CCD image sensors have a unique structure in which the back of the active area is finely ground to allow light to enter from
the back surface. This structure ensures high UV sensitivity and quantum efficiency because incident light need not pass through the
electrodes.
*2: The FFT-CCD was originally designed as a two-dimensional image sensor. However, it can be operated like a linear image sensor
having a large active area by transferring all the pixel signals in the vertical direction to the horizontal register (this is referred to as
line binning).
