Princeton Infrared Technologies, Inc. (PIRT) is focused on supplying Shortwave Infrared detectors to both the commercial and defense markets. PIRT is a fabless semiconductor company focusing on design and integration of our own semiconductor designs. The products are manufactured by leveraging more established semiconductor fabrication facilities to produce our designed detector products in quantity with high quality at low cost. This model is used through the semiconductor industry, but not in the infrared detector business.

In the past the infrared imaging industry had no commercial foundries to manufacture the "exotic" materials used to produce IR detectors, but that today is no longer true. Now that fabrication facilities can manufacture infrared parts, our fabless model will lead to much lower cost and improved devices for both the defense and the commercial sectors.

PIRT is also leveraging advance Silicon CMOS technologies to enable PIRT to gain the advantages of technology developed for the commercial arena. Having the fabrication of our detector designs conducted at an outside foundry allows PIRT to concentrate on design of the product, managing the process, and conducting final assembly, which minimizes the equipment and staff needed, thus overhead costs. This is the model used by almost all modern electronic manufacturers.

Shortwave Infrared (SWIR) Imaging using lattice matched InGaAs (In0.53Ga0.47As) provides some of the lowest noise imaging material for imaging in the SWIR. Princeton Infrared Technologies, Inc. (PIRT) has detectors that image from 0.5 to 1.7 μm, which are useful for a variety of commercial and defense applications. These include detecting moisture, determining plastic types, as well as imaging lasers. We sell these imagers by themselves, in packages, as well as in complete camera systems.
