Laser Components GmbHRequest Info
OLCHING, Germany, Dec. 2, 2014 — Laser Components Count SLaser Components’ Count-S is the newest addition to the company’s Count series of photon counters.

The new module features a large active area of 500 µm to facilitate better focusing, and is also passively quenched. Its dead time of approximately 1 µs yields a maximum count rate of up to 1 million counts per second. The dark count rates of the Count-S range between 1000 and 5000 cps.

It is designed for use in research that involves quantum optics and information.

quantum optics
The area of optics in which quantum theory is used to describe light in discrete units or ‘quanta’ of energy known as photons. First observed by Albert Einstein’s photoelectric effect, this particle description of light is the foundation for describing the transfer of energy (i.e. absorption and emission) in light matter interaction.
photon counter
A device used to evaluate the luminance of a surface by determining the number of photons emitted from a sample surface area.
