Overview
APDCAM is the smallest member of the APDCAM family of devices from Fusion Instruments.
APDCAM uses a single Hamamatsu S8550 4×8 pixel Avalanche Photodiode (APD) array or two 4×4 Hamamatsu MPPC arrays where all 32 pixels have their individual low noise analog amplifiers and digitizers. The output data is sent over a Gigabit Ethernet connection which is also used for control from the computer. The common 200-400 V detector bias voltage is generated in APDCAM, this way the detector gain can be set from the computer. For stable gain the detector temperature is regulated by a Peltier cooler/heater to a set point +- 15 degrees from ambient temperature. An electromechanical shutter and built-in calibration light helps in the practical setup and operation of the device.
Features
- 32 pixels in 4×8 matrix, individual low noise amplifiers and ADCs for each pixel.

- Quantum efficiency max. 85% (APD, in red), 40% (MPPC in green)
- Micro-lens array for detector (for APD, optional).
- Detector gain: 2-50 for APD, 107 for MPPC, adjustable by detector bias voltage.
