C7020_15 Datasheet, PDF (1/8 Pages) Hamamatsu Corporation – Designed for front-illuminated CCD area image

CCD multichannel detector heads
C7020/C7021/C7025 series
Designed for front-illuminated CCD area image
sensors
The C7020/C7021/C7025 series are high sensitivity multichannel detector heads intended for use with front-illuminated CCD area
image sensors (S9970/S9971/S9972/S9973 series). The C7020 series is designed for non-cooled CCD, while the C7021/C7025 se-
ries for thermoelectric cooled CCD. All of the C7020/C7021/C7025 series contain a low-noise driver circuit that operates on input of
simple external signals. Mounting holes are provided on the front panel for attaching to other devices such as spectrometers.
The C7021/C7025 series also include a highly stable temperature control circuit that cools the sensor to a preset temperature (Ts=-10
°C) as soon as the power is turned on. If the cooler fails and causes overheating, the internal protection circuit automatically turns
off the power to ensure safety. Despite the compact size, the housing configuration is designed for good heat dissipation.
As an option, HAMAMATSU also provides the C7557-01 controller for multichannel detector heads. Using the dedicated software for
the C7557-01 allows easy control and data acquisition of a multichannel detector head from a PC.

Selection guide
The table below shows CCD area image sensors applicable for C7020/C7021/C7025 series.
Since C7020/C7021/C7025 series do not include a CCD area image sensor, so select the desired sensor and order it separately.

*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 area image sensor 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).
