Infrared Athermal Lens Description:
Focal Length 75mm F1.0 Long Wave Athermal Lens For 640x512-17um Detector.
8-12um Wavelength Infrared Sights Lens, Drone Monitor Infrared Lens, Car Monitor Infrared Lens For 17um Sensor.
The principle of Athermal lens is widely used in infrared thermal imaging technology.
When performing infrared thermal imaging, we need an infrared electronic camera to capture the image, and the camera must be equipped with a suitable thermal imaging lens.
Typically, lenses used in thermal imaging employ non-thermalization techniques to form the image.
Infrared imaging requires collecting the light signal detected by the lens assembly and transmitting it to the detector. Subsequently, the detector and its corresponding reverse channel convert the optical signal into an electrical signal.
The choice of lens material in an optical system depends on the particular detector and its intended application.
Different infrared lens materials have unique characteristics and require different processing methods and equipment.

FAQ:
What Is An AR Coating?
Anti-reflective coating (English: Anti-reflective coating, AR) is a surface optical coating that increases transmittance by reducing light reflection. In complex optical systems, it can improve contrast by reducing scattered light in the system.
Many coatings include transparent film structures with different refractive indices. The thickness of the film determines the wavelength of the reflected light that it acts on. When light is reflected twice on the AR coating, it will interfere with the original reflected light, thereby weakening the reflected light. According to the conservation of energy, the energy of light does not change. Therefore, when the reflected light decreases, the transmitted light increases. This is the principle of AR coating. Generally, when choosing an AR coating, you need to determine the wavelength, such as infrared, visible and ultraviolet.
