If conventional detectors are unable to distinguish between signal and noise, then single-photon detectors are used. These detectors have a high detection efficiency at a low dark count rate like LASER COMPONENTS‘ silicon-based single photon avalanche diodes (SPADs). When equipped with electronics, they turn into easy-to-handle photon counting modules. 

Optimized for wavelengths in the near infrared, LASER COMPONENTS introduces the single photon counting module COUNT^® NIR. It has a notable detection efficiency of 60% at 810 nm and achieves a maximum detection efficiency of almost 80% at 700 nm. Products with dark count rates of less than 50 counts per second are available.  The COUNT^® NIR is equipped with a gating function protecting the module between measurements. The power is connected using a 12 V power supply.
The COUNT^® NIR development supports applications in fundamental research where light quanta play a crucial role. Many experiments are conducted in the wavelength range around 810 nm, in quantum optics, fluorescence and quantum information.
