InGaAs linear image sensors

InGaAs linear image sensors
G10768 series
Near infrared image sensor (0.9 to 1.7 μm)
with 1024 pixels and high-speed line rate
The G10768 series is a 1024-channel, high-speed infrared image sensor designed for applications such as foreign object
screening and medical diagnostic equipment where a multichannel high-speed line rate is required. The signal processing circuit uses CTIA (capacitive transimpedance amplifiers) that allow signal readout while simultaneously integrating signals in all
pixels via sample-and-hold circuits. A high-speed line rate is achieved through 8 output ports.

Notes:
· Sensor video output is fully differential, so use fully differential buffers to receive the sensor output.
· To obtain the fastest line rate, the odd and even pixels should be operated simultaneously so that the 8-port output is read out in parallel.

G10768 series
Multichannel detector head C10854 (sold separately)
The C10854 is a multichannel detector head suitable for applications where high-speed infrared imaging is required, such as sorting
machines and SD-OCT (spectral domain-optical coherence tomography). The Hamamatsu G10768 series InGaAs near-infrared linear
image sensor (sold separately) can be easily installed in the C10854.
This C10854 comes with application software (Dcam-CL) that runs on Windows 7 (32-bit, 64-bit). It can be used to control the
C10854 from the PC. The application software also includes a function library exclusively for the C10854, allowing you to develop
your own software more efficiently.

Electrostatic countermeasures
This device has a built-in protection circuit against static electrical charges. However, to prevent destroying the device with electrostatic
charges, take countermeasures such as grounding yourself, the workbench and tools to prevent static discharges. Also protect this device from surge voltages which might be caused by peripheral equipment.
