Description of LWIR Lens:
For Long Wave infrared (LWIR) lenses, here are some common material
properties:
- Chemical resistance: LWIR lens materials usually need to have good
chemical stability and be able to resist corrosive substances such
as humidity, oxidants, acids and bases in the atmosphere.
- Optical materials: LWIR lenses usually use special optical
materials, such as zinc selenide (ZnSe), zinc sulfide (ZnS),
cadmium sulfide (CdS), indium cadmium sulfide (InCdS), etc.
- Thermal properties: LWIR lens materials need to have high thermal
conductivity in order to effectively dissipate heat during use and
avoid performance degradation caused by overheating.
- Mechanical strength: LWIR lens materials need to have sufficient
mechanical strength and hardness to ensure that they can resist
external pressure, vibration and stress during use, and are not
prone to rupture or deformation.
- Refractive index: The refractive index of the LWIR lens material
determines the speed and focusing ability of light through the
lens.
Features of LWIR Lens:
Long Wave infrared (LWIR) lenses have the following advantages:
- High infrared transmittance: These materials have good
transmittance in the LWIR band and can effectively transmit
long-wave infrared radiation.
- Wide wavelength range: These materials have a wide operating
wavelength range in the LWIR band and can adapt to the wavelength
requirements of infrared radiation in different applications.
- Mechanical strength and hardness: These materials usually have a
certain mechanical strength and hardness, can resist external
pressure, vibration and stress, not easy to crack or deformation.
- Chemical resistance: These materials usually have good chemical
stability and can resist corrosive substances such as humidity,
oxidants, acids and bases in the atmosphere.
- Excellent thermal properties: LWIR lens materials usually have high
thermal conductivity, which can effectively dissipate heat and
avoid performance degradation caused by overheating.

Applications of LWIR Lens:
Long wave infrared (LWIR) lens materials are widely used in the
following applications:
- Aerospace: LWIR lenses also have applications in the aerospace
sector for infrared detection, target tracking, navigation and
control systems.
- Thermal imaging: LWIR lenses are often used in thermal imaging
systems to detect and display the thermal energy distribution of
objects.
- Environmental monitoring: LWIR lenses can be used for environmental
monitoring, such as monitoring atmospheric temperature, surface
temperature, ocean temperature, etc.
- Infrared temperature measurement: Because LWIR lens can receive
infrared radiation, it is widely used in the field of industrial
temperature measurement.
- Military and security: LWIR lenses are widely used in the military
and security fields for night vision observation, target detection
and identification, thermal imaging devices, etc.
- Medical diagnosis: Infrared thermal imaging technology in the
medical field can be used to diagnose and monitor diseases.
