G9494-256D_15 Datasheet, PDF (1/8 Pages) Hamamatsu Corporation – Near infrared image sensors (0.9 to 1.7 m) with high-speed data rate

InGaAs linear image sensors
G9494-256D/-512D
Near infrared image sensors (0.9 to 1.7 μm)
with high-speed data rate
Hamamatsu provides high-speed, near infrared image sensors designed for detectors used in on-line foreign object
inspection equipment. These image sensors use square-shaped pixels that are ideally suited for software processing in
pattern recognition systems. The signal processing circuit employs CTIA (Capacitive Trans-Impedance Amplifier) method to
perform simultaneous charge integration on all pixels, so there is no time lag among the pixel output signals.
