With the rapid development of science and technology, near infrared lights have become an indispensable part of our daily life. As a type of electromagnetic wave with a wavelength between 700nm and 2500nm, near infrared lights have a wide range of applications in various fields. In this article, we will introduce the industry of near infrared lights, covering its definition, characteristics, applications, and future development trends.

Definition and Characteristics of Near Infrared Lights

Near infrared lights, also known as NIR lights, are a kind of electromagnetic wave with a wavelength between 700nm and 2500nm. They are invisible to the human eye and can only be perceived by special equipment. Compared with visible light, near infrared lights have higher energy and can penetrate through certain materials. The following are the main characteristics of near infrared lights:

• Short wavelength: Near infrared lights have a shorter wavelength than visible light, which makes them more likely to be absorbed by materials.
• High energy: The energy of near infrared lights is higher than that of visible light, which can cause various physical and chemical reactions.
• Invisible: Near infrared lights are invisible to the human eye, so they can be used in special applications without affecting people's vision.
