Designed for multi-channel spectro-photometry, G1682x devices are front-illuminated InGaAs sensors intended for real-time analysis in R&D and industry across 0.9 to 2.1µm.
They “maintain low dark current through zero bias operation, effectively eliminating the need for cooling”, said the company.
The output is a single video stream, allowing users to conduct simultaneous analyses across the pixels.
Inside is an InGaAs photodiode array and a CMOS chip which offers two settings (16 or 160nV/electron) “through external voltage”, said the company, which is not yet publishing the device data sheets – Electronics Weekly has asked what this means, so watch this space if it is important to you.
Power is required at 3.3V.
