Laser Components, PicoQuant to Develop Photon Counters
Sep 2010
OLCHING, Germany, Sept. 16, 2010 — Laser and optoelectronic components and services manufacturer Laser Components GmbH announced it has forged a strategic alliance with PicoQuant GmbH of Berlin, to develop and commercialize photon counters.

Working together, Laser Components DG Inc. will manufacture and develop the highly sensitive avalanche photodiodes (APDs), while PicoQuant will supply the electronics for the photon counters.

The companies will develop two different series: the photon counters for non-time-resolved applications, trademarked Count through Laser Components’ worldwide distributors, and the –Spad, a module series for time-resolved applications that is available through PicoQuant.

Assembly and subsequent testing of both types of modules are being performed at each of the company’s headquarters.

Both series feature never-before-seen quantum efficiency and extremely low dark count rates, said both companies.

“PicoQuant possesses great application know-how and enjoys an excellent reputation worldwide in the photon counting market,” said Patrick Paul, general manager of Laser Components. “Even though the APD technology, which is at the heart of the system, is our own, it is important for us to bring in another partner. The synergies of this alliance are promising.”

PicoQuant manufactures picosecond diode lasers and time-resolved fluorescence systems.

That branch of science involved in the study and utilization of the motion, emissions and behaviors of currents of electrical energy flowing through gases, vacuums, semiconductors and conductors, not to be confused with electrics, which deals primarily with the conduction of large currents of electricity through metals.
The emission of light or other electromagnetic radiation of longer wavelengths by a substance as a result of the absorption of some other radiation of shorter wavelengths, provided the emission continues only as long as the stimulus producing it is maintained. In other words, fluorescence is the luminescence that persists for less than about 10-8 s after excitation.
A sub-field of photonics that pertains to an electronic device that responds to optical power, emits or modifies optical radiation, or utilizes optical radiation for its internal operation. Any device that functions as an electrical-to-optical or optical-to-electrical transducer. Electro-optic often is used erroneously as a synonym.
photon counter
A device used to evaluate the luminance of a surface by determining the number of photons emitted from a sample surface area.
