Image sensor for DWDM wavelength monitor

G9201 to G9204 series InGaAs linear image sensors are specifically designed as detectors for monitoring WDM in optical communications. These linear image sensors consist of an InGaAs photodiode array with each pixel connected to a charge amplifier array comprised of CMOS transistors, a CDS circuit, an offset compensation circuit, a shift register and a timing generator. These sensors deliver high sensitivity and stable operation in the near infrared spectral range. The package is hermetically sealed for high reliability and the window has an anti-reflective coating for efficient light detection.
