Considerations for Thermal Lens Selection

Many factors must be considered when choosing an infrared lens for a thermal imaging camera. These include knowledge of the technology being used and of the intended application for the imager. It is also essential to have a good idea of what results must be achieved in light of the price range budgeted for a new IR camera lens (the entire lens assembly mounted to the camera). Knowing these critical aspects of IR lenses can facilitate the selection process.
