About Princeton Infrared Technologies, Inc.

At Princeton Infrared Technologies, Inc., we design and manufacture shortwave infrared (SWIR) cameras and imaging arrays. We focus on indium gallium arsenide (InGaAs) technology and all of our products are created under strict testing and quality control guidelines, providing innovative and cost-effective detectors. Our cutting-edge products allow – 

Shortwave (SWIR) Infrared Products and Demo

In this video, you will learn all about the short wave infrared (SWIR) imaging wavelength and see a live demo of a SWIR camera. You will see how our SWIR camera can see through glass and plastics and learn why SWIR imaging can help you with your imaging needs.

Shortwave Infrared Soldering Iron Video

Short Wave Infrared (SWIR) is traditionally not used for thermal imaging but SWIR imagers are very good at imaging and measuring the temperature of objects hotter than 150 degrees Celsius. In this video, we are looking at a hot soldering iron using a visible camera, a longwave infrared microbolometer, and Princeton Infrared Technologies' 1280MVCam SWIR InGaAs Camera.

Princeton Infrared Technologies, Inc. SWIR Cameras - Water vs. Acetone

In this video, you will see how our short wave infrared (SWIR) cameras can see the difference between water and acetone.

Coffee Beans and Contaminant Detection in Short Wave Infrared (SWIR)

Short wave infrared (SWIR) has been used in many contaminant detection applications. Objects may be the same color in the visible, but outside the visible wavelength band, their reflective properties can be very different. This enables SWIR cameras to detect the contaminants and allow systems to remove them from the processing line. In this video, the coffee beans, rocks, and twigs are all brown or are dark in color on a black background. Under 1400nm light, the coffee beans are very reflective, while the other objects are not, which enables the system to eliminate the contaminants easily.

Seeing Through Silicon Wafers with a Short Wave Infrared (SWIR) Camera Video

Short wave infrared (SWIR) cameras from Princeton Infrared Technologies, Inc. can see through silicon wafers. SWIR cameras can see through the opaque wafer to show the processed circuits and also show defects and structural imperfections. SWIR cameras are ideal for inspecting silicon solar panels, processed silicon wafers like computer chips and raw silicon raw ingots.

Determining Detergent Fill Levels with Short Wave Infrared (SWIR) Video

In this video, you will see how a short wave infrared (SWIR) camera from Princeton Infrared Technologies, Inc. can see through the plastic of a blue detergent bottle to help determine fill levels.
