PerkinElmer SliK avalanche photodiode decapsulated

The package (about 15 mm in diameter at the outer rim) contains the APD and thermistor atop a two-stage thermoelectric cooler. It was extracted from a detector module SPCM-AQR-13-FC, s/n 7069. We killed this APD in an experiment, so it was dead anyway and could be opened.
