How Long Wave Infrared Uncooled Athermalization Continuous Zoom Lens Works
- Optical zoom: The zoom group in the lens changes the distance with other lens groups by moving, so as to achieve continuous change of focal length.
- Uncooled: The infrared thermal radiation of the object is used for imaging, and no cooling equipment is required.

What is the difference between LWIR and MWIR?
1. Wavelength range
LWIR has a wavelength of 8-14 microns, which is closer to the microwave region.
MWIR has a wavelength of 3-5 microns, which is between short-wave infrared and LWIR.Atmospheric transmission
LWIR has a strong ability to penetrate fog, dust and other obstructions, and has a certain degree of penetration for light rain and snow, because the atmosphere is more transparent to it.
MWIR can also penetrate the atmosphere, but is greatly affected by components such as water vapor, and its transmission capacity is reduced at high humidity.Thermal sensitivity and target detection
LWIR is sensitive to small temperature differences and can effectively detect objects with a small temperature difference from the background, such as the human body in a cold environment.
MWIR is more suitable for detecting high-temperature objects and is used in situations where the temperature difference between the target and the background is large, such as industrial high-temperature components.Application scenarios
LWIR is used for security night vision, building heat loss inspection, and finding survivors during rescue.
MWIR is used for target acquisition and tracking of military equipment and industrial high-temperature process monitoring.
