IMAGE SENSOR
CCD multichannel detector head
C7020, C7021, C7025
Designed for front-illuminated CCD area image sensors
C7020, C7021 and C7025 are high sensitivity multichannel detector heads for use with front-illuminated FFT-CCD area image sensors. C7020 is
designed for the non-cooled front-illuminated CCD image sensors (S7010 series), while C7021 and C7025 for the TE-cooled CCD image sensors
(S7011/S7015 series) for detection at even lower light levels. C7020, C7021 and C7025 incorporate a low-noise driver/amplifier circuit that
provide reliable operation from simple external signals. C7021 and C7025 also include 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 builtin 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.
The table below shows front-illuminated CCD image sensors for C7020, C7021 and C7025. C7020, C7021 and C7025 do not come with a CCD
image sensor, so select the desired sensor and order it separately.
Multichannel detector head controller C7310-02 is also available.

*1: The FFT-CCD (full frame transfer CCD) has charge transfer sections that are also used as light receiving areas, being
different from interline transfer CCD (IT-CCD) commonly used in video cameras. Compared to the IT-CCD, the FFT-CCD
offers advantages of low dark current, a 100 % open area ratio and low image lag.
*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).
