The COUNT® NIR Counts Single Photons from 400 - 1000 nm

Single Photon Counter from LASER COMPONENTS

(PresseBox) ( Olching, )
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 to easy-to-handle photon counting modules.

Especially made 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 further more a maximum detection effiency of almost 80% at 700 nm. Dark count rates of less than 50 photons per second are common. To operate this module, TTL pulses can be used: for this purpose, the COUNT®s are equipped with a gating input. The power is connected using a 12 V power supply.

The COUNT® NIR development has been pushed because of experiments in fundamental research where light quanta play a crucial role. Many experiments are conducted in the wavelength range around 810 nm, such as, for example, in quantum optics and quantum information.
