Laser Safety Glasses

High power laser pointers and laser modules are both entertaining and widely used for many applications. There's just one major problem, but with the spread of high power lasers. high-power lasers can cause serious and permanent damage to your eyes in less time than it takes to blink. Governments and health agencies are aware of this and the use and ownership of lasers increasingly regulated to reduce the dangers of lasers.

The best solution if the danger of high power laser for laser safety glasses or goggles 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 wavelengths of 500nm to 540nm, which offers protection against lasers green.

With safety glasses, laser quality depends on two points. How well they block light at a certain wavelength and how much visibility they provide. The ability to block the light is determined by optical density or OD for short. Over the OD, the more the light is blocked.

For most applications the preferred OD is 3 to 4. If the optical density is less than three, not enough energy laser beams is blocked. If the visibility of the OD higher than 4, while wearing laser safety glasses will be too diminished.

Laser safety glasses are designed to protect users against accidental exposure to UV laser is the deliberate exposure extended. After a few seconds of exposure to a laser beam, the dyes in the glasses will be destroyed and the glasses will no longer provide protection.
