InGaAs linear image sensor

G14237-512WA

null

Near infrared sensors (0.85 to 1.45 μm)

The G14237-512WA is an InGaAs linear image sensor designed for Raman spectroscopy measurement using a 1064 nm laser. Designed specifi cally for measuring the Raman spectral range, the cutoff wavelength has been reduced from that of the previous product (G11508-512SA) to achieve low dark current. This product consists of an InGaAs photodiode array and CMOS chips made up of charge amplifiers, offset compensation circuit, shift register, and timing generator. The charge amplifi ers consist of CMOS transistor arrays and are connected to each pixel of the InGaAs photodiode array. The signal from each pixel is read out in charge integration mode, which provides high sensitivity and stable operation in the near infrared region. The package is hermetically sealed for excellent reliability. The signal processing circuit on the CMOS chip can be set to one of four conversion effi ciency (CE) settings using an external voltage.


Features
- Low noise, extremely low dark current
   [1/10 or less than that of the previous product (cutoff wavelength: 1.7 μm)]
- Selectable from four conversion efficiency types
- Built-in saturation countermeasure circuit
- Built-in CDS circuit
- Built-in thermistor
- Easy operation (built-in timing generator)
- High resolution: 25 μm pitch
