Traditional mechanical door locks generally use keys to open the door, while the main unlocking methods of smart door locks include: fingerprint recognition, password unlocking, NFC device unlocking, mobile APP unlocking, etc. These unlocking methods are mature, safe and stable. So, what role does laser play in smart door locks? Laser is mainly used in smart [...]
The laser colors we use for positioning include red light, green light, blue light, blue-violet light, etc. The commonly used light spots are one-line, cross-line, dot-shaped light spots, concentric circles, etc. The multi-ring laser converts the laser beam into multiple concentric rings with controllable radius. The diameter and size of the rings can be adjusted, and [...]
Many times, our naked eyes cannot see all the dust. Only when exposed to a strong ray of light or a specific light will the tiny particles in the air become apparent. Hence, the invention of the green light-displaying vacuum cleaner. Green light for vacuum cleaners - vacuum cleaners with green light dust display technology. [...]
Laser line marking instrument is a high-brightness laser line formed by beam expansion of a semiconductor laser. The color of the line is divided into many categories, mainly green and red. The marking line produces a bright, clear, uniform, and highly collimated marking line by projecting a laser line on the object. The user can cut, [...]
The laser sight is an auxiliary aiming device that has the functions of aiming, indicating, deterring, and transmitting information. Usually the lasers used for aiming are green laser, red laser and infrared laser. Green laser: The most common green lasers have wavelengths of 520nm and 532nm. The human eye is sensitive to the wavelength of green [...]
As one of the earliest infrared technologies applied in the security industry, laser infrared technology is mainly used in specific places such as forest fire prevention, oil fields and border surveillance. So, what are the advantages of laser technology in the security field? Laser has strong penetrating power, very low false alarm rate, and long [...]
The underwater environment is special and puts forward higher requirements for detection, communication and other technologies. As an advanced optical technology, laser technology has the characteristics of good directionality, concentrated energy, and long transmission distance, and has broad application prospects in the underwater field. The wavelength selection of laser in the underwater field is [...]
Laser has the characteristics of monochromaticity, high brightness and collimation, and is widely used in various fields such as industrial production. Laser ranging is a method of distance measurement using laser technology. It calculates distance by measuring the time it takes for a laser pulse from a laser to reach the target and back. Advantages of [...]
A laser consists of a laser working material, an excitation system and an optical vibration cavity. It is a device that can produce laser radiation. Its application fields are very wide, covering many aspects such as industry, medical care, scientific research, military, communications and so on. Industrial field The application of lasers in the industrial [...]
Laser is a highly concentrated light beam that is monochromatic, directional and brighter than ordinary light sources. Laser Applications Industrial field: laser cutting, laser welding, laser marking, laser engraving, etc., can improve production efficiency and product quality. Medical field: laser surgery, laser treatment, laser beauty, etc., which have the advantages of less bleeding, less [...]
