The mechanism of laser sterilization is based on the interaction between laser and substance. Laser can be used for sterilization and disinfection. Different doses and wavelengths can kill different bacteria, viruses and various parasites.

Characteristics of lasers with different wavelengths Blue laser: The penetration depth is the shallowest.Green laser: The penetrating power of tissue is stronger than blue light intensity.

Infrared ray is an electromagnetic wave with a wavelength between microwave and visible light. It has the same essence as radio wave and visible light. Its wavelength is between 770 nm and 1 mm, and it is located outside the red light in spectrum.

Food packaging has the highest requirements in the packaging industry, and it is closely related to people's daily life, so it has always been highly concerned by people. With the continuous improvement of living standards.

Ultra-long-distance infrared laser night vision system is composed of high-power semiconductor laser LD, driving controller, optical beam expanding and collimating lens, camera and its long focal length lens, transmission system and monitor, etc.

The fusion of laser technology and welding technology realizes a non-contact welding method, which uses a small amount of heat input and a small heat affected zone to weld multi-layer metals.

Laser is a great invention in the 20th century, and it is called the fastest knife, the most accurate ruler and the brightest light. Laser (light amplification by stimulated emission of radiation), which means stimulated radiation light amplification, describes the principle of laser generation.

In the laser diode market, red and blue semiconductor diodes are mature and widely used in display devices. Although green semiconductor laser technology has made some progress recently.

Medical science is the earliest, most extensive and most active frontier subject in which laser technology is applied. There are dozens of varieties of laser medical equipment used clinically.

Visible light refers to the electromagnetic wave that can cause vision, and it is the part of the electromagnetic spectrum that can be perceived by human eyes.Invisible light is a general concept.
