InGaAs detectors offer fast response and high sensibility

LASER COMPONENTS is a manufacturer of extended InGaAs detectors. From their research and production facility in Arizona, they supply customers all over the world with 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 suit 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.
