7.5mm F/1.0 LWIR Athermal Fixed Lens For 320x240-12um

Manual Focus Lens Description:

1. Focal Length 7.5mm F1.0 Long Wave Infrared Germanium Lens, Infrared Athermal Lens For Drone Monitor.

2. Fixed focal length, generally used in places where it is not easy to focus.

The principle of Athermal lens is widely used in infrared thermal imaging technology.

When doing infrared thermal imaging, we need an infrared electronic camera to capture images, and the camera must be equipped with a suitable thermal imaging lens.

Typically, lenses used in thermal imaging use athermalization techniques to form the image.

Infrared imaging requires collecting the light signal detected by the lens assembly and transmitting it to a detector. Subsequently, the detector and its corresponding back channel convert the optical signal into an electrical signal.

The choice of lens material in the 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.
