38mm F/1.3 Infrared Aiming Lens For 640x480-17um and 384x288-17um

Infrared Aiming Lens Description:

Focal Length 38mm F1.3 Infrared Aiming Lens Thermal Sight Lens For 640x480-17um and 384x288-17um Detector.

8-12um Long Wave Infrared Germanium Lens Apply to Infrared Sights, Thermal Imager, Thermal Sight Scope, Monitor Camera, Infrared Camera, etc.

Infrared multi-layer Coating technology (IR Coating), infrared anti-reflection:

Multilayer composite coating technology can reduce light scattering loss, increase the transmittance of the lens, and make the picture clearer.

At the same time, the anti-reflection ability of 750-1000nm wavelength light wave is improved.

The surface of the lens is usually dark green.

Infrared multilayer Coating technology (IR Coating) can improve the transmittance of near-infrared light, which can be the icing on the cake for infrared lenses to achieve better HD.

FAQ:

What materials are suitable for making infrared lenses?

When designing infrared optical elements, various factors related to the optical material used must be considered. These factors include refraction properties, light transport, non-thermal properties, hardness/durability, environmental sensitivity, weight/density, manufacturing technology, and cost. Some of these factors are still interrelated. For example, for some materials, their optical transmittance is higher at room temperature, but decreases at higher temperatures. With all these factors in mind, material selection needs to be carefully considered when designing infrared optical elements. Available materials are: germanium (Ge), silicon (Si), gallium arsenide (GaAs) and cadmium telluride (CdTe); Zinc compounds, such as zinc sulfide (ZnS) and zinc selenide (ZnSe); Water-soluble crystals such as potassium bromide (KBr), sodium chloride (NaCl), and potassium chloride (KCl); Magnesium fluoride (MgF 2), calcium fluoride (CaF 2), barium fluoride (BaF 2) and other fluorides. And other materials, such as fused quartz and sapphire; Chalcogenide glass, etc
