Single Photon Counting Module Count Series
SPCM-APD series Single Photon Counting Module APD operated in the Geiger mode, are used to detect single photos over the wavelength range of 350nm to 1060nm. The SPCM-APD series has been developed to offer a unique combination of high quantum efficiency, wide dynamic range and ease of use for photon counting applications.
The photodiode is both thermoelectrically cooled and temperature controlled, ensuring stabilized performance despite ambient temperature changes. Operating temperature range has been increased and the module (case temperature) will operated from -5℃ to +28℃ 。
The dead time of the SPCM-APD is approximately 33ns, thereby increasing linearity and improving the dynamic range of the module. Timing resolution of the module was also improved significantly.
The SPCM-APD has very high Photon Detection Efficiency (PDE) from blue range to yellow range.The SPCM-APD operated in the Geiger mode, so the detector provides gains of up to 106--108.
