Single Photon Counting Modules
LASER COMPONENTS Germany GmbH
In 2010, LASER COMPONENTS introduced yet another innovative product into the market: complete single photon counting modules that meet all customer demands regarding high quantum efficiency and very low dark count rates.
At the heart of the COUNT® modules is a Geiger-mode silicon avalanche photodiode, which was specifically developed by the LASER COMPONENTS Detector Group, Inc. This APD is one of the lowest-noise photodiodes on the market and features an excellent quantum efficiency.
Automated measuring station
for COUNT modules
For quality control purposes, LASER COMPONENTS and a SPAD manufacturer Swabian Instruments set up a state-of-the-art measuring station in 2021.
At its heart is the Time Tagger Ultra, a highly sensitive TCSPC system (Time-Correlated Single-Photon Counting), which is supplemented by ultra-short pulsed diode lasers, high-precision reference power meters and computer-controlled motion tables. All important values can be determined in the system, such as jitter, dark count rate, afterpulsing, dead time and detection efficiency.
Standard measurements are performed for the wavelengths 405 nm, 505 nm, 670 nm and 804 nm. Up to twelve COUNT® modules with or without fiber coupling can be tested simultaneously. We simulate different scenarios to test efficiency in your application field.
