Fearures of Infrared Lens:
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: 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.
