The ultrafast photodetectors are best suited for measurement of optical waveforms from DC to 110GHz. Various models feature rise times as short as 1ps and cover the spectral range from 800 to 1700 nm.
All photodiodes are enclosed in compact and solid aluminum housings and can be biased with a battery or an external power supply.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 high-gain amplifiers, the high-speed photodetectors are an advantageous alternative to the expensive and cumbersome avalanche photodiodes.
