12 Considerations for Thermal IR Camera Lens Selection

When developing a solution that requires a thermal imager, or infrared (IR) camera, engineers, procurement agents, and program managers must consider many factors. Application, waveband, minimum resolution, pixel size, protective housing, and ability to scale production are just a few. One element that will impact many of these decisions is the IR camera lens.
