Characteristics of Infrared Lens:
Our selection of Infrared Lens comprises lenses with manual adjustment, fixed adjustment, and motorized LWIR lenses, with focal lengths ranging from 3.8 to 250. We offer various interface options, including M34x0.5, M45x1, M34x0.5, M34x0.75, c-mount, and flange. The distance between the lens and the observed object varies from 13.3 to 61.26.
LWIR lenses commonly utilize germanium. Its exceptional durability, chemically inert properties, and high Knoop hardness make it an excellent choice for challenging surroundings. However, germanium lenses may experience significant defocusing due to thermal drift under specific conditions. In situations where temperature changes are expected, we recommend using our ZnSe LWIR lenses, which offer more stable focusing even with significant temperature variations.
Our LWIR zoom lenses deliver sharp, high-resolution images throughout the entire zoom range, making them perfect for machine vision applications that require detailed visuals. We provide both discrete and continuous zoom lenses.

FAQ:
What Materials Are Suitable For Infrared Lenses?
When designing infrared optical components, various factors related to the optical materials used must be considered. These factors include refractive properties, optical transmission, 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 high at room temperature, but decreases at higher temperatures. Considering all these factors, when designing infrared optical components, careful consideration of material selection is required. 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); fluorides such as magnesium fluoride (MgF2), calcium fluoride (CaF2) and barium fluoride (BaF2); and other materials, Such as fused silica and sapphire; chalcogenide glass, etc.
