Do I need protective glasses to use the laser pointer?
There are some great laser pointers on the market. From pointers that can shoot a mile to pointers that can light a match in the bedroom, you can choose powerful laser pointers, and most of them are not toys. However, the question remains: Do I need to wear protective glasses for the laser pointer? Laser pointer protective glasses is a kind of special glasses that can prevent or reduce laser damage to human eyes. Laser protective goggles are highly efficient and safe goggles, which are suitable for a variety of lasers and laser pointers. This series of optical safety glasses is comfortable, beautiful, safe and reliable to wear. Its optical safety performance fully meets GJB1762-93. The laser safety glasses are reflective and absorptive, which can protect laser and strong light of a specific band in all directions. Applicable to a variety of laser equipment. The visible light transmittance is above 70% and the optical density is above 5.0 (OD+5, OD+6).

Today, with the increasing development of laser skills, different effects will be presented in different application areas, especially laser protective glasses. Wearing laser protective glasses is to better assist the eyes to prevent external forces. Each type of laser protective glasses They have their own characteristics. Generally, they can only protect against lasers of one wavelength, and a few can protect against lasers of two or more wavelengths. To cover lasers in all wavelength ranges, a material that blocks any visible light, ultraviolet and infrared radiation is needed. This material is like wearing a steel plate that blocks all light but cannot be used by itself. The wider the wavelength range that the laser protective glasses of the green laser pointer needs to protect, the more difficult it is to manufacture. For example, it is easy to protect the ultraviolet band from 190nm to 360nm. However, when the protection is from the visible light band to the infrared band, the wider the coverage wavelength, the filter lens will not be able to pass.
