Uses of Long-Wave Infrared (LWIR) Lenses:
LWIR lenses find application in LWIR cameras, which can capture light that cannot be seen with the naked eye. This makes them highly valuable in a wide range of important uses. For example, our lenses are employed in thermal imaging systems for quality control purposes in factories. They also allow for predictive maintenance in industrial environments, enabling the identification of potential issues before they become major problems. Additionally, LWIR lenses enable clear surveillance imaging even in the presence of smoke or fog.
Moreover, LWIR lenses are utilized in the detection of gas leaks, helping to prevent hazardous situations from escalating. In medical applications, the combination of LWIR lenses and thermal imaging provides a non-invasive and dependable method for detecting changes in temperature at a cellular level. This enables medical professionals to identify abnormalities and assess various conditions, such as breast cancer, brain tumors, diabetes, and burn trauma.

What are DLC and AR Coatings?
Diamond-like carbon (DLC) film is an amorphous carbon film. The film 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.
In various hard films, DLC film can be positioned as a film material with high hardness, excellent wear resistance and low friction coefficient.
AR (anti-reflection) film does not change the absorption rate of the lens itself. It can only increase the transmittance by reducing the reflectivity on both sides of the lens, which is called "reflection and anti-reflection".
Light is an electromagnetic wave. By matching the refractive index and thickness of the AR film, the light generates multiple beam interferences in the AR film - cancelling interference on the upper surface and phasing interference on the lower surface.
