Where to Buy Photodetectors

The 710 Series are high sensitivity, low noise photodetector-amplifier modules that offer the flexibility of incorporating a variety of silicon or InGaAs, PIN or APD photodetectors. AMI also offers the capability of integrating other detectors on a custom basis.

Ultrafast photodetectors from ALPHALAS for measurement of optical waveforms with rise times starting from 10 ps and total spectral coverage from 170 to 2600 nm (VUV to IR) have bandwidths from DC up to 30 GHz. Configurations include free-space, fiber receptacle or SM-fiber-pigtailed options and have compact metal housings for noise immunity. The UV-extended versions of the Si photodiodes are the only commercial products that cover the spectral range from 170 to 1100 nm with a rise time < 50 ps. For maximum flexibility, most models are not internally terminated. A 50 Ohm external termination supports the highest speed operation, while a high impedance load generates large amplitude signals. Applications include pulse form and duration measurement, mode beating monitoring and heterodyne measurements. Balanced photodiodes complement the large selection of more than 70 unique models.

Our D2250 2.2–5.0 µm single wavelength detector is super-fast (up to 10 GHz bandwidth) and ultra-sensitive (NEP of a few fW/√Hz).

Our D2250’s are based upon a new measuring paradigm where mid-infrared light is converted into near-visible light and then measured with conventional near-visible detector technology.

CSRayzer CR2000AH-1550-70M includes a 200 μm InGaAs avalanche photodiode and a hybrid preamplifier for the use in high speed, ultra-low light detection, in laser range finding, LIDAR and free space communications.

Gentec Electro-Optics offers a great range of power detectors based on silicon or germanium photodiodes for powers up to 750 mW.

Menlo Systems offers a series of photodetectors for lowest light level signals. From avalanche to PIN photodiodes, you can find the detector that is best for your specific application.
