uv-visible-near ir Detectors for Photon Counting and Laser Radar

Silicon APDs for single photon counting - devices with 50 mm active area and VERY LOW Dark Count Rates now available

The id100-series from id Quantique in Switzerland is a room temperature 350 to 900 nm silicon APD with extremely fast (40 ps) response and excellent timing stability up to count rates of at least 10 MHz.  A companion product is the id150-15-1x10, a 10-element linear array.  In fact, in some applications these have better timing accuracy than the Hamamatsu R3809U MCP PMT, at a much lower cost.  The active area is of course much smaller than that of the R3809U.  .Applications include single molecule spectroscopy and time resolved confocal microscopy.  For complete info and test data on id Quantique Si APDs, click here.  For prices, phone or email us.

In addition to the silicon photon counting APDs mentioned above, id Quantique also manufactures SINGLE PHOTON COUNTING APDS at TELECOM WAVELENGTHS (1100 to 1600 nm) and SHORT PULSE LASER SOURCES for 1310 and 1550 nm.

We also have a very complete line of PMT-based and MCP-PMT based single photon counters for TCSPC and LIDAR.  These include Hamamatsu tubes selected from their many models for best TCSPC performance and higher level assemblies from Becker & Hickl in Berlin.  Click here for a large 90+ page pdf with complete details including preamps and other accessories.
