High-speed Photodetectors

The ALPHLAS UPD series of free space incident ultrafast photodetectors is best suited for spatial light waveforms ranging from DC to 25GHzThe measurement. Multiple products are available for selection, providing optical pulse signals with a minimum rise time of 15ps for detection, covering the spectral range from 170 to 2600nm.All detectors are enclosed in a compact and sturdy peroxide polarized aluminum casing, and can be powered by batteries or external power sources.It is the only commercial product that can provide high-speed silicon detectors extending from 170 to 1100 nm to the ultraviolet spectral range.Another unique type of UV sensitive InGaAs detector that can be used to detect lasers in the range of 350 to 1700 nanometersPulse, therefore, has the widest spectral range and the highest response speed.

Perfect impedance matching and state-of-the-art microwave technology ensure the fidelity of the measured pulse waveform. Users can freely use 50 ΩMatch resistors to detect the highest response speed. Or to obtain a large signal response curve, a high impedance load can be added. Guaranteed UPDThe product provides maximum flexibility for different applications.Combined with BBA series broadband high gain amplifiers, high-speed photodetectors are a viable alternative to expensive and cumbersome avalanche photodiodesExcellent choice. UPD's series of 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.
