Compact and low cost 1D InGaAs image sensor, allowing installation in a portable equipment

  • Publisher

 Hamamatsu has developed the low cost 1D InGaAs image sensor G13913 series by employing a small size LCC (Leadless Chip-Carrier) package. 1D InGAs image sensors have been used widely for near infrared spectroscopy. There is growing demand on a sensor for downsizing and current consumption reduction.
 A back-illuminated structure InGaAs array chip of 128 ch or 256 ch is adopted to the G13913 series, realizing both small size and low cost. Unlike a conventional 1D InGaAs image sensor mainly for a large size instrument, the new features of the G13913 series will make installation in a portable equipment possible.
