Ultrafast Photodetectors UPD Series NEW MODELS: Faster Rise Times & Wider Wavelength Ranges 42 Unique Models T he UPD series of ultrafast photodetectors are best suited for measurement of optical waveforms from DC to 25 GHz. Various models feature rise times as short as 15 ps and cover the spectral range from 170 to 2600 nm. All photodetectors 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 350 to 1700 nm, thus having the widest spectral range and the highest speed commercially available. Perfect impedance matching and state-of-the-art microwave technology assure pulse form measurements without any ringing or artefacts. The customer is free to use a 50 Ω terminating resistor for highest speed operation, or a high impedance load for obtaining large signals. This guarantees maximum flexibility for diverse applications. In combination with our BBA series of wideband high-gain amplifiers, the high-speed photodetectors are an advantageous alternative to the expensive and cumbersome avalanche photodiodes. The UPD series high-speed photodetectors are indispensable tools for laser and photonics research. Features Ultra High-Speed Operation Rise Times: star...
