Characteristics of Athermal Infrared Lens:
Our selection of Infrared Lens includes lenses with manual focus, fixed focus, and motorized LWIR lenses. The focal length options we have in stock range from 3.8 to 250. We provide various interface options such as M34x0.5, M45x1, M34x0.5, M34x0.75, c-mount, and flange. The distance between the lens and the object being viewed varies from 13.3 to 61.26.
LWIR lenses often use Germanium. Its strong durability, unreactive chemical properties, and high Knoop hardness make it a suitable choice for harsh environments. However, one disadvantage of Germanium lenses is their vulnerability to significant blurring caused by changes in temperature in certain situations. In cases where temperature fluctuations are expected, we recommend our ZnSe LWIR lenses, which maintain a more stable focus even with large temperature changes.
Our LWIR zoom lenses provide clear and high-resolution images throughout the entire zoom range. They are particularly suitable for machine vision applications that require precise imagery. We offer both distinct and smooth zoom lenses.

FAQ:
What Are DLC And AR Coating?
Diamond-like carbon (DLC) membrane is an amorphous carbon membrane. The membrane contains a certain number of sp3 bonds, giving it a series of excellent properties close to diamond. It has the advantages of low deposition temperature and large area deposition.
Among various hard membranes, DLC membrane can be positioned as a membrane material with high hardness and excellent wear resistance and low coefficient of friction.
AR (Anti-Reflection) membrane cannot change the absorption rate of the lens itself. It can only increase the transmittance by reducing the reflectance on both sides of the lens, which is the so-called "reflection and antireflection".
Light is an electromagnetic wave. By matching the refractive index and thickness of the AR membrane, the light produces multi-beam interference in the AR membrane-destructive interference on the upper surface and constructive interference on the lower surface.
