The UPD series of ultrafast photodetectors are best suited for measuring of optical waveforms from DC to 10 GHz. Various models feature rise times from 30 to 500 ps and cover the spectral range from 170 to 2000 nm.
All photodiodes are enclosed in compact and solid aluminum housings and can be biased with a battery or an external power supply.
The UV-extended versions of the silicon type photodetectors are the only commercial products that cover the spectral range from 170 to 1100 nm.
Another type of unique UV-sensitive InGaAs photodetectors can be used for detecting laser pulses in the range from 250 to 1700 nm, thus having the widest spectral range and the highest speed commercially available.
