PRESS RELEASE

COUNTblue to launch at BiOS & PW2011 in San Francisco
Single Photon Counting Module for shorter wavelengths

LASER COMPONENTS expands its award-winning COUNT series of single photon counting modules to include the new COUNTblue devices. These combine the phenomenally low count rates of the existing modules with even higher detection efficiencies at shorter wavelengths. Over 60% of incoming photons can be detected at 405 nm, over 65% in the green, while the detection efficiency in the red is typically >50%. The excellent short wavelength performance makes the COUNTblue the ideal choice for fluorescence measurement and microscopy applications.

The COUNTblue features the same robust design as the existing modules and the optional fiber connector allows easy plug&play operation.

Come and see the COUNTblue and talk to our product specialists at Photonics West 2011 (Moscone Center, San Francisco, January 25-27).

LASER COMPONENTS is specialized in the development, manufacture, and sale of components and services for the laser and opto-electronics industries. With sales offices in four different countries, the company has served its customers since 1982. In-house production at six locations in Germany, Canada, and the USA began in 1986 and is meanwhile responsible for about half of its turnover. Currently, the family-run business employs more than 130 people worldwide.
