What is IR Lenses?
IR lenses are made from infrared materials, such as Germanium, silicon, ZnSe, ZnS, CaF2, MaF2, LiF,  Yutai offers not only common shape optical lens, but also offers special shape lenses, such as the lenses with stage or hole.

What is the application of IR Lenses?
1. Thermal imaging: security monitoring and fire protection.
2. Military and defense equipment for night vision: infrared guidance, reconnaissance and surveillance.
3. Medical equipment: infrared thermal imager and laser therapy.
4. Used for optical path transmission and focusing in infrared spectrometers.
5. Infrared communication and optical fiber communication.
6. Focusing and processing of infrared lasers.
7. Environmental monitoring: for optical transmission and detection in infrared gas analyzers, meteorological observation.
8. Consumer electronics: infrared cameras and infrared remote controls.
9. Aerospace: for Earth and planetary observation and environmental monitoring.
10. Infrared sensors and detection systems for night vision systems and autonomous driving in the automotive industry.
