Infrared Athermal Lens Description:
1. Focal Length 52mm F1.0 Long Wave Infrared Germanium Lens For 640x480-12um Detector
2. 8-12um Long Wave IR Athermal Lens For Infrared Hunting Scope, Infrared Camera, Monitor.
3. Fixed Focal Focal Length, Easy operation without manual adjustment.
Germanium lenses are known for their unique features:
When it comes to infrared camera lenses, germanium glass is the first choice due to its excellent refractive index.
Unlike ordinary optical glass, it is only transparent to infrared light, which makes it ideal for capturing images in low-light environments.
This special property makes it possible to detect animals and plants that cannot be seen with the naked eye.
However, germanium is a rare element and its content is limited, which makes it costly to extract and produce lenses.
As a result, infrared camera lenses typically cost more than standard camera lenses made of man-made materials.
