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 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 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.
