C7973

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. Features Applications *1 Cooling temperature: -10 ± 0.05 ˚C (Ta=10 to 35 ˚C) l Simple signal input operation l Compact configuration l Designed for back-thinned CCD area image sensor l Line binning operation/area scanning operation *2 l Driver/amplifier circuit for low noise CCD operation l Highly stable temperature controller l Fluorescence spectroscopy l Raman spectroscopy l Other low-light-level detection The table below shows CCD area image sensors applicable for C7973. Since C7973 does not include a  CCD area image sensor, so select the desired sensor and order it  separately. CCD area image sensor Type No. S7963 S7964 S7965 Number of pixels 80 × 72 124 × 56 232 × 56 Number of active pixels 64 × 64 108 × 48 216 × 48 *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, backthinned 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).
