The innovations made by LASER COMPONENTS Detector Group do not stop. A new detector 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 extremely low noise, SUR-series avalanche photodiodes (APDs) are suited for measurements in photometry or in analytical systems as well as for fluorescence measurements.
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 255 nm and 1000 nm.
SUR500. At 400 nm the SUR500 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 of just a few nm in thickness.
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.
