Features of LWIR Lens:
LWIR (Long Wave infrared) lenses have several advantages in the field of infrared imaging:
- Thermal energy detection: The LWIR band covers the thermal energy radiation emitted by the object, allowing the LWIR lens to detect and measure the temperature distribution of the object in a non-contact manner.
- Wide application: LWIR lens has a wide range of applications in industrial, construction, medical, military and aerospace fields. Whether for temperature monitoring, fault diagnosis, target identification or night vision observation, the LWIR lens provides accurate and useful infrared information.
- Affordable: LWIR lenses are generally less expensive to manufacture than some other infrared band lenses.
- Lightweight: Compared to other infrared wavelength lenses, LWIR lenses are usually made of lightweight materials, making the entire infrared imaging equipment more lightweight and easy to carry.
- Night vision capability: LWIR lens performs well in night vision applications due to LWIR band's ability to detect thermal energy.
- Good transmittance: The material of LWIR lens has good infrared transmittance and can transmit infrared radiation in LWIR band.
Applications of LWIR Lens:
