Hamamatsu Introduce Latest InGaAs Linear Image Sensor Designed for Near Infrared Multichannel Spectrophotometry

Hamamatsu Photonics introduces the new InGaAs linear image sensor consisting of 512 pixels with a 25 µm pixel pitch. The G12230-512WB employs two InGaAs chips of different cut-off wavelengths, giving it a spectral response range of 950 to 2150 nm.

As each pixel from the InGaAs photodiode array is read in charge integration mode from the CMOS chip, this allows for high sensitivity and stable operation within a wide spectral response range.

The package is hermetically sealed providing excellent reliability. The device has two external conversion efficiency types which can be selected for your application from the signal processing circuit on the CMOS chip.
