InGaAs Detectors

18 Jul 2017

LASER COMPONENTS is a world leading manufacturer of extended InGaAs detectors.

From our research and production facility in Arizona we supply customers all over the

world with these industrial grade quantum detectors. The semiconductor material

absorbs incident IR photons in the intrinsic region generating electron hole pairs which

are collected at external electrodes. Photovoltaic detectors are an excellent choice

in many applications due to their high sensitivity, fast response, low noise and wide

dynamic range.

A typical standard product is the IG19 with a peak wavelength of 1.75 microns,

making it ideal for applications that cannot be met spectrally with a regular InGaAs

photodiode; the detectors have active areas ranging in diameter from 0.25 to

3.00mm. Responsivity can be improved dramatically by reducing the operating

temperature of the device with a thermo electric cooler.

The devices are manufactured in standard TO style packages and have long expected

lifetimes making them ideal for fit and forget applications such as gas analysis, laser

monitoring, moisture measurement and tuneable diode laser spectroscopy.
