L3 CCD Systems
The XCAM very high speed, low noise L3 CCD system has the following key features:
- Extremely high speed operation: CCD97 up to 15 MHz, and CCD201 up to 25 MHz High speed means faster frame rates for both full frame and when reading out sub arrays: for example the CCD 97 can readout 552 x 132 pixels at about 160 Hz without any binning
- By using focal plane masks even faster frame rates are possible; eg 110 x 132 @ 800 Hz
- Extremely Low Clock-induced Charge due to our Unique Analysis System Background equivalent number: 0.0005 electrons per pixel in a 50 ms exposure time cf 0.005 electrons per pixel in a 30 ms exposure time quoted by other manufacturers
- Use with gains of up to 4000 or gain turned off for normal CCD operation
- Optical Photon-Counting
- Systems are individually optimised for specific CCD for best performance
- Systems available cryogenically cooled for optical, or for vacuum operation for X-ray
XCAM specialises in custom systems; this high speed electronics can be built into a system to suit your experiment. For further details, please contact us for information specific to your application.
