The germanium lens is renowned for its unique qualities:
In the realm of lenses for infrared cameras, Sulfur glass stands out as the preferred option due to its remarkable refractive index.
Unlike regular optical glass, it exclusively allows infrared light to pass through, making it ideal for capturing images in dimly lit environments.
This extraordinary attribute enables the detection of hidden animals and plants that would otherwise go unnoticed by the human eye.
Nevertheless, germanium is a scarce element found only in limited quantities, resulting in costly extraction and lens production.
Consequently, the price of infrared camera lenses tends to be higher compared to standard lenses crafted from synthetic materials.
