Applications of Long-Wave Infrared (LWIR) Lenses:
LWIR lenses have various uses in LWIR cameras, which can capture light that is invisible to the naked eye. This makes them extremely valuable in a wide range of important applications. For instance, our lenses are utilized in thermal imaging systems for quality control purposes in factories. They also allow for proactive maintenance in industrial settings, enabling the detection of potential issues before they become major concerns. Furthermore, LWIR lenses enable clear surveillance imaging even in the presence of smoke or fog.
Additionally, LWIR lenses are employed in the identification of gas leaks, aiding in the prevention of dangerous situations from escalating. In medical fields, the combination of LWIR lenses and thermal imaging provides a non-intrusive and reliable method for detecting temperature changes at a cellular level. This allows medical professionals to identify abnormalities and evaluate various conditions, including breast cancer, brain tumors, diabetes, and burn injuries.

FAQ:
What are the DLC and AR Coating?
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.
