LThe highest possible quantum efficiency and the highest possible count rate were the specifications for the photon counting modules produced in-house.
Laser Components has formed a strategic partnership with PicoQuant GmbH, to develop these photon counting modules of the highest quality.
Laser Components COUNT counting modules achieve an unmatched quantum efficiency of over 70 % in the red region! Another advantage of this photon counter over other existing modules on the market is its significantly higher quantum efficiency in the blue region of the spectrum.
The COUNT series of modules is based on an avalanche photodiode used in Geiger mode, which was specially developed by sister company Laser Components Detector Group, Inc. specifically for this series. It is one of the lowest noise APDs on the market. Together with its electronics, which have been optimized down to the last detail, this APD is the heart of the COUNT module. As of October 1, 2010, the standard modules are available with count rates from 20 to 250 counts. Modules with hits < 10 c/s (strokes per second) are also available on request.
These modules are supplied either with an easy-to-use FC fiber optic connection, with a fiber core diameter of up to 105µm, or in free optical form. Thanks to its compact housing and its plug & play compatibility with other photon counters available on the market, replacing an existing photon counter with the COUNT is a breeze.
