Excelitas C30902SH

General Description The C30902SH is avalanche photodiode selected for low noise fabricated with a double-diffused “reach-through” structure. This structure provides high responsivity between 400 and 1000 nm as well as extremely fast rise and fall times at all wavelengths. The responsivity of the device is independent of modulation frequency up to about 800 MHz. The detector chip is hermetically-sealed behind a flat glass window in a modified TO-18 package. The useful diameter of the photosensitive surface is 0.5 mm. 0.475mm photosensitive diameter, dead time filter 20ns, photon detection efficiency >70% at 700nm Applications Single molecule detection High throughput single photon experiments LIDAR Photon correlation spectroscopy Astronomical observation Optical range finding Adaptive optics Ultra sensitive fluorescence Particle sizing
