The IPD4A is a highly-integrated, true gated charge integrator to be attached directly to up to four photodiodes. After a trigger pulse, up to four inputs are integrated simultaneously for an adjustable amount of time (boxcar integrator). The measurement is digitized with integrated 20 bit analog-to-digital converters and transferred over the USB link to a computer.
The IPD4A is compatible with a wide range of photodiodes including both silicon (Si)-based and InGaAs-based ones with various sensitive areas. While we supply the IPD4A with certain high quality detectors from Hamamatsu, you can also have the full choice over wavelength and sensitive area by specifiying or directly providing the photodiodes to be integrated into the IPD4A.
The IPD4A comes in a rugged aluminum case and is fully USB-powered.
