The innovations mady by Laser Components Detectors Group do not stop. A
new detector, the SUR500, was developed specifically for (bio-)medical
applications in which the smallest signals in the short-wave UV/blue
spectral range have to be detected.
Due to their very high sensitivity and their extremely low noise,
SUR-series avalanche photodiodes are suited for measurements in
photometry or in analytical systems as well as for fluorescence
In addition to measurements in the optimized blue and UV spectral range
the photodiode can be used for measurements in the entire wavelength
range between 200 nm and 1000 nm.
The SUR500 performance is excellent. At 400 nm the detector has a noise
equivalent power (NEP) of typically only 9 fW/sqrt(Hz) at a sensitivity
of about 28 A/W. Such values can only be achieved with a special
reach-through structure developed by LASER COMPONENTS.
The SUR series is currently available with an active diameter of 500
µm. Other low noise versions at 1.5 mm and 3 mm will be available
soon. The TO housings, which were optimized specifically for the UV
range, are hermetically sealed and very compact.
