Avalanche Photodiodes
These avalanche photodiodes (APDs) are silicon photodiodes with an internal gain mechanism. As with a conventional photodiode, absorption of incident photons creates electron-hole pairs. A high reverse bias voltage creates a strong internal electric field, which accelerates the electrons through the silicon crystal lattice and produces secondary electrons by impact ionization. The resulting electron avalanche can produce gain factors up to several hundred.

Low Input Bias Current Op Amps (≤100 pA)
Low input bias current op amps are required whenever the difference of currents or voltage is small and needs to be measured accurately. These op amps are used so that the signal is not loaded down by the input of the op amps. Low input bias current op amps are critical for interfacing sensors in applications from photodiodes, pH meters, or other electrometer related functions to downstream electronics.

PIN Diodes
PIN photodiodes convert light to current – without a bias voltage having to be applied. Silicon is commonly used as an inexpensive detector material in the Vis range. For higher demands, InGaAs is used; it covers the widest spectral range from the Vis to the NIR. We offer silicon carbide as a “solar-blind” detector specifically for the UV range.

Transducers For Photodiodes
Photodiodes convert incoming electromagnetic radiation into electrical charge carriers. If photodiodes are short circuited an electrical current (photocurrent) proportional to the incident radiation intensity (number of photons per second) is induced. These photocurrents are generally small and cover the range from femtoampere (fA) to microampere (µA). Signal transducers transform this weak photocurrent to robust standard signals for reliable data transmission and simple data acquisition.

PIN Photodiode
PIN photodiode is a kind of photo detector, it can convert optical signals into electrical signals.This technology was invented in the latest of 1950's. There are three regions in this type of diode. There is a p-region an intrinsic region and an n-region. The p-region and n-region are comparatively heavily doped than the p-region and n-region of usual p-n diodes. The width of the intrinsic region should be larger than the space charge width of a normal p-n junction. The PIN photo diode operates with an applied reverse bias voltage and when the reverse bias is applied, the space charge region must cover the intrinsic region completely. Electron hole pairs are generated in the space charge region by photon absorption. The switching speed of frequency response of photo diode is inversely proportional to the life time. The switching speed can be enhanced by a small minority carrier lifetime. For the photo detector applications where the speed of response is important, the depletion region width should be made as large as possible for small minority carrier lifetime as a result the switch speed also increases.
