InGaAs linear image sensor



Near infrared image sensor (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. This image sensor uses square-shaped pixels that are ideally suited for software processing in pattern recognition systems. The signal processing circuit employs CTIA (Capacitive Transfer Impedance Amplifier) method to perform simultaneous charge integration on all pixels, so there is no time lag among the pixel output signals.

- High-speed data rate: 2 MHz typ.
- Selectable conversion gain (Cf=0.1 pF, 1 pF)
- Pixel size G9494-256D: 50 × 50 μm
- CMOS readout circuit incorporated
- Low dark current
- Room temperature operation
