高速光電探測器
The UPD series of ultrafast photo-detectors are best suited for mea-surement 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 hous-ings 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.

Notes:
¹⁾ The diffuse window reduces the positioning accuracy requirements and increases the damage threshold at the cost
of a reduced sensitivity by a factor of approx. three to five. Recommended for high peak power lasers only.
²⁾ This model has negative output. All other models have positive output by default but may be ordered
with negative output if required.
³⁾ With TEC cooling module， non-standard housing.
⁴⁾ Modified material with increased blue / UV sensitivity.
