Follow on Google News | Laser Safety Glasses & Goggles - Essential Protectin against High Power LasersHigh power lasers can cause serious and permanent damage to a persons eyes so laser safety glasses are an essential accessory. The glasses need to match the wavelength of the laser, provide suitable protection and adequate visibility.
By: Frank The best solution though to the danger of high powered lasers is laser safety glasses or goggle for eye protection. Laser safety glasses work by using a polymer containing dyes that block light over a specific range of colors or wavelengths. For example some laser safety glasses will block light with a wavelength of 500nm to 540nm which provides protection from green lasers. With laser safety glasses, quality depends on two points. How well they block light at a certain wavelength and how much visibility they provide. The ability to block light is determined by optical density or OD for short. The higher the OD, the more light that is blocked. For most applications the preferred OD is from 3 to 4. If the OD is lower than 3, not enough of the laser beams energy is blocked. If the OD higher than 4, visibility while wearing the safety glasses will be too impaired. Laser safety glasses are designed to protect users from accidental exposure to laser beams not deliberate extended exposure. After several seconds exposure to a laser beam, the dyes in the glasses will be destroyed and the glasses will no longer provide protection.
