The unique features of the germanium lens are widely recognized:
In the realm of lenses created for infrared cameras, germanium glass stands out as the favored option due to its exceptional refractive index.
In contrast to ordinary optical glass, it exclusively permits the passage of infrared light, making it ideal for capturing images in dimly lit situations.
This exceptional attribute allows for the detection of concealed animals and plants that would otherwise go unnoticed by human vision.
However, germanium is a scarce element found in limited quantities, leading to costly extraction and lens production.
Consequently, the price of infrared camera lenses tends to be higher compared to standard lenses made from artificial materials.
