A New, Never-Before-Seen Product

Not very long on the market and already we are introducing another new innovation: the single photon counting module COUNT^blue, which is produced in house.

Blue Enhanced
The COUNT^blue series achieves a quantum efficiency of 60 % in the blue spectral range, which has never been done before. Significantly higher than modules from other manufacturers, our COUNT products typically achieve a quantum efficiency of 70 % in the yellow and green wavelengths.

The heart of the COUNT series is a blue-enhanced silicon Geiger mode APD developed specifically for this series. It is the lowest-noise APD on the market. Together with electronics optimized down to the last detail, dark count rates of 10-250 counts per second (c/s) are available.

Use
For applications in fluorescence measurement, the COUNT^blue series makes it possible to significantly improve performance compared to applications employing older-generation single photon counting modules (SPCMs).

Moreover, these photon counters are particularly well suited for measurements across the entire wavelength range from 350-1000 nm.

Typical fields of application include general photon counting, spectroscopy, fluorescence lifetime imaging microscopy (FLIM), confocal fluorescence microscopy, single molecule detection (SMD), FCS, and quantum cryptography.

System Integration
These modules are available with an FC connection for optical fibers with a core diameter up to 105 µm or as a free-beam version. They are
plug & play compatible with standard photon counters available on the market. Existing counting modules can, therefore, easily be replaced by our COUNT, which has been done successfully on several occasions by our customers.

COUNT Wins NASA Tech Briefs Award
The awards ceremony for the NASA Tech Briefs Awards was held at Photonics West 2011. LASER COMPONENTS was awarded this prize for the first time and accepted it for its COUNT series single photon counting modules. “We are very proud that we were able to make such an impact with such a young product,” said Patrick Paul, managing director of the LASER COMPONENTS Group.

The winning product is selected based on feedback from readers of the journal.
