Infrared cameras don’t work the same way as regular, visible light cameras. Regular cameras function more or less the same way as a human eye, receiving radiation in the visible light spectrum and turning it into an image. Infrared cameras, on the other hand, make images from heat, aka infrared or thermal radiation, instead of visible light.

The opposite can be true. Germanium, a semi-metallic element similar to silicon, is completely opaque in the visible world:

Infrared lensmaterial

Infrared radiation behaves very differently from visible light. Because of this, infrared camera lenses need to be made from different materials than regular cameras. The properties for a given material in the visible world might have no bearing on its properties in the infrared world—glass, for instance, is extremely transparent to radiation in the visible spectrum, but in infrared, glass is completely opaque:

IR camera lenses are made out of substances like germanium, or other materials with low absorption in the infrared spectrum. But why is it necessary to use these specialized components instead of a more common substance like glass?

is an option for Graphics3D and related functions that specifies the properties of point light sources for simulated illumination.

It’s for this reason that FLIR camera lenses are made of germanium or other materials that are transparent in the infrared spectrum.
