Hamamatsu Photonics photodiodes cover a broad spectral range, from near-infrared and ultraviolet wavelengths to high-energy regions. Photodiodes are available in metal, ceramic, and plastic packages, as well as module types. Custom designs are also available.

AMS Techno­logies carries an exceptionally broad range of photodiodes (PDs), based on various materials, cooled or uncooled, featuring single devices as well as photodiode arrays or assemblies:

• silicon photodiodes: general-purpose PDs, APDs, high-speed, fast-response or wavelength-enhanced sensitivity variants, duo- and tetra-lateral devices, multi-element PDs and arrays, PD assemblies with filters, TIAs or multiple (sandwich) PDs
• InGaAs photodiodes: general-purpose PDs, PIN, APDs, large active area, segmented or back-illuminated, PD arrays,PD assemblies including PD-amplifier hybrids, mini-DIL optical receivers or pigtails
• GaAs photodiode arrays, GaAs PD/amplifier hybrids
• devices based on HgCdTe, PbS or PbSe
• PD chips based on Si, InGaAs, GaP and AlGaAs

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.

Lasers, Optics, Electronics. Made in Germany.

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.
