Middle Wave Infrared Lens Description:
Focal Length 25mm F2.0 Infrared Germanium Lens For 640x512-15um Detector
3-5um Middle Wave Infrared Lens Apply to Thermal Imager, Infrared Sights, Monitor Camera, Drone Monitor, Thermal Image Monitoring and Observation Equipment, etc.
MWIR lenses are highly sensitive and provide excellent contrast while minimizing background noise. They are perfect for imaging over long distances, high-temperature radiometry, and scientific research.
These lenses are particularly well-suited for use in marine and high humidity environments, as well as harsh outdoor conditions. They are commonly used for airport perimeter security, vessel traffic monitoring, and critical infrastructure protection.
In addition, MWIR lenses are highly versatile and are ideal for use in laboratories. They offer ultra-high sensitivity, ultra-low noise, and precise temperature measurement, making them ideal for meeting even the most demanding testing requirements.

FAQ:
What Is An AR Coating?
Anti-reflective coating (English: Anti-reflective coating, AR) is a surface optical coating that increases transmittance by reducing light reflection. In complex optical systems, it can improve contrast by reducing scattered light in the system.
Many coatings include transparent film structures with different refractive indices. The thickness of the film determines the wavelength of the reflected light that it acts on. When light is reflected twice on the AR coating, it will interfere with the original reflected light, thereby weakening the reflected light. According to the conservation of energy, the energy of light does not change. Therefore, when the reflected light decreases, the transmitted light increases. This is the principle of AR coating. Generally, when choosing an AR coating, you need to determine the wavelength, such as infrared, visible and ultraviolet.
