COUNT
Record-breaking Dark Count Rate, Highest Quantum Efficiency
COUNT
COUNT on us! The COUNT photon counter features the highest quantum efficiency available and record-breaking dark count rates.
Facts about the COUNT Photon Counter
Laser Components’ single photon counting modules (SPCM) achieve an unrivaled quantum efficiency of over 70% in the red region. Another advantage of these photon counters over modules currently available on the market is their significantly higher quantum efficiency in the blue spectral range. In addition, these modules are perfectly suited for measurements across the entire wavelength range from 400-1000 nm.
Special Geiger-Mode APDs
The COUNT series is based on a silicon Geiger-mode APD developed specifically for this series. It is one of the lowest-noise APDs on the market. Together with electronics that has been optimized down to the smallest detail, this APD represents the heart of the COUNT module. Available in a compact housing, the photon counter can be integrated into your application without a problem.
Product Variations
Standard modules are available with dark count rates ranging from 20 to 250 counts. Modules with <10 cps (counts per second) are also available.
These modules either come with an easy-to-use FC connection for optical fibers that have a core diameter of up to 105 µm or as a free-beam module. Thanks to its compact housing and plug & play compatibility with photon counters currently available on the market, replacing existing SPCMs with the COUNT module is child’s play.
