Thermal Sight Lens Description:
Manually adjust the infrared lens to facilitate observation of objects at different distances, generally used for telescopes, infrared sights scope, infrared cameras, thermal imaging cameras and other items.
Long Wave Infrared (LWIR) lens applications:
LWIR lenses, also known as long wave infrared wavelength range 8000-12000nm lenses, are specially designed lenses. At Rising Optics, we produce high quality long wave infrared lenses for a wide range of applications including medical, industrial, security and defence.
Long wave infrared cameras use long wave infrared lenses to capture light that cannot be seen by the naked eye. This characteristic makes them extremely valuable in a variety of important applications. For example, our lenses are used in thermal imaging systems to ensure quality control in factories. They also contribute to proactive maintenance in industrial environments, enabling the identification of potential issues before they escalate into major issues. In addition, even in the presence of smoke or fog, the long wave infrared lens guarantees clear monitoring imaging.

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.
