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 sizingCONTACT US FOR VOLUME PRICING

XProduct SKU: PYS 3228 TC G1/G20-3641-P
Single-Element Pyroelectric Detectors are often applied for temperature and gas measuring applications in one-channel or dual-channel variants, which is then one output per element. Single-Element variants are offered as thermally compensated devices. The principle of Gas monitor application is called NDIR. NDIR requires Detectors with narrow-band optical filters. Excelitas provides a range of suited filter windows for those gases which show an absoption band in the IR spectral range.

Excelitas C30659 Series - 900/1060/1550/1550E
Si and InGaAs APD Preamplifier Modules Excelitas Technologies’ C30659 Series includes a Si or InGaAs Avalanche Photodiode (APD) with a hybrid preamplifier, in the same hermetically-sealed TO-8 package, to allow for ultra-low noise operation. The Si APDs used in these devices are the same as used in Excelitas’ C30817EH, C30902EH, C30954EH and C30956EH products, while the InGaAs APDs are used in the C30645EH and C30662EH products. These detectors provide very good response between 830 and 1550 nm and very fast rise- and fall-times at all wavelengths. The preamplifier section of the module uses a very low noise GaAs FET front end designed to operate at higher transimpedance than Excelitas’ regular C30950 Series. Excelitas’ InGaAs C30659-1550E Preamplifier Modules, with 1550 nm peak response, are designed to exhibit higher damage thresholds, thus providing greater resilience when exposed to high optical power densities. Customization of the C30659 Series of APD Preamplifier Modules is available to meet your specific design challenges; modifications include bandwidth and gain optimization, use of different APDs, FC-connectorized packaging.
