PDI-400 Integrating Photodiode Module

PDI-400 Integrating Photodiode Module

High sensitivity integrating detector from Becker & Hickl for pulsed light signals. The PDI-400 includes a high performance photodiode, a low noise charge sensitive amplifier and an active high pass filter.

Pulse energy measurement Low noise high dynamic range Sensitivity in the fJ range

The PDI-400 is insensitive to roomlight. Most of the amplifier noise and low frequency background signals are rejected with integrated filtering. Its high sensitivity, low noise and wide dynamic range makes it extremely useful in all applications where accurate and reproducable measurements of light pulse energies are essential. When used in conjunction with the bh Boxcar devices, the PDI-400 does not require a special power supply.
