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.

Reduce Development Time by Two Years
This paper reviews the traditional challenges of MWIR imaging platform design and illustrates how leveraging a single solution provider can reduce time to market, complexity, and affordability while also improving size, weight, and performance (SWaP).
