7.5mm F/1.0 Germanium LWIR Manual Focus Lens For Infrared Sight

Application of infrared lens:

1. Airborne

2. Security Monitoring

3. Maritime surveillance

4. Thermal Imaging

5. Thermal Imager (Portable)

6. Defense

7. Enhance vision

With the rapid development of infrared optical technology, infrared lenses are increasingly used in civil, industrial, military and other fields.

Because temperature changes will affect the surface shape of the infrared lens optical components, the refractive index of the optical components, the focal shift of the lens, etc., resulting in poor imaging quality and lens blur. Image and contrast are reduced.

Therefore, manual focus lens design is one of the essential links in the design process of infrared lens.

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
