InGaAs linear image sensor
G16824-256DG
Non-cooled type, single video line (256 pixels) Near infrared image sensor (0.9 to 1.9 µm)
The G16824-256DG is a compact InGaAs linear image sensor designed for near infrared multichannel spectrophotometry. It consists of an InGaAs photodiode array and a CMOS chip that contains charge amplifiers, offset compensation circuits, shift registers, and a timing generator. Charge amplifiers are configured with CMOS transistor arrays and are connected to each pixel of the InGaAs photodiode array. Since the signal from each pixel is read in charge integration mode, high sensitivity and stable operation are attained in the near infrared region. The signal processing circuit on the CMOS chip enables the selection of an optimum conversion efficiency (CE) for your application from the available two types using external voltage.
This product is smaller than previous products and uncooled. Previous long-wavelength types required TE cooling to reduce dark current. This product achieves lower dark current while being uncooled by zero bias operation compared to previous products.
