Overview
APDCAM-10G is a modular Avalanche Photodiode (APD) detector camera capable of using up to four Hamamatsu S-8550 4×8 pixel APD arrays. This way various pixel configurations are available: 4×16, 4×32, 8×8, 8×16. Additionally the FC64 version uses 64 individual detectors with SMA fibre coupling. The photo below shows the 8×16 pixel configuration with 128 pixels.
Each APD pixel in APDCAM-10G has its own low noise amplifier and Analog to Digital Converter (ADC). The amplifier parameters are matched to the expected photon flux and target measurement frequency of the application in order to provide the optimal Signal to Noise Ratio. The data stream resulting from the ADCs is directly transmitted to the computer via a 10 Gbit Ethernet connection which allows the exceptionally fast 4 MHz sampling rate for 128 channels. The same interface is used for controlling the camera operation.
APDCAM-10G contains the usual complete infrastructure found in the APDCAM family: temperature controlled detectors, calibration lights, various clock and trigger schemes. Additionally the device can be equipped with up to 4 optical fibres arranged around the detectors for spectral measurements and/or calibration.
Like other devices in the APDCAM family this device can also be ordered with micro-lens array and magnetic field hardened electronics.
