Semiconductor Infrared Laser
Semiconductor infrared lasers have a wide range of applications in various fields. In infrared spectroscopy analysis, they can be used for gas detection, chemical analysis, and material characterization. In infrared imaging, they can be used for infrared thermal imagers, night vision devices, and security monitoring. In infrared communication, they can be used for high-speed data transmission and fiber optic communication. In addition, semiconductor infrared lasers are also used in fields such as medical diagnosis, environmental monitoring, and industrial testing. Our company spends on customizing various types of infrared lasers.
