New laser protection glasses highlights

In the presentlife we all know that the laser has a lot of role, but have to say that thelaser is harmful to our body, so we will choose to use Laser safety glasses, ofcourse, its type is not the same. Today to talk about the new Laser safetyglasses highlights.

   Laserprotection mirror anti-laser radiation protection mirror micro-explosion typelaser protection lens lens coated with a layer of specific high transparencychemical film, when the incident laser energy exceeds a certain value, thechemical explosion black, so that the lens completely opaque, so Protect youreyes from laser damage. The goggles are more suitable for high power continuouslasers. Laser protection mirror using non-linear optical principle to achievelaser protection has become a hot topic in many countries. Non-linear made of this material are not onlysensitive to wavelength but also sensitive to light intensity. It can achievethe same laser wavelength, high light density of light and high lighttransparency of the two indicators of low light Unity and balance.

   Itis reported that carbon-carbon polymer (C60 or C70) has a large and very fastnonlinear optical effect, but also a material that achieves anti-satietyabsorption at lower light energy, made of this material The light limitingdevice reduces the transmittance as the intensity of the incident light increases,thereby limiting the output light below a certain energy threshold. Lasersafety glasses of this material has a high visible light transmittance of morethan 60%, but the lower optical density is generally below 3, and theanti-laser damage threshold is generally low. It is characterized by a weaklaser when the absorption of less, was high transmission, and strong laserincident, the absorption, was low transmission. Since the nonlinear absorptioncomes from the electronic mechanism, the response is fast and the response timeis in the order of picoseconds. Anti-Laser Radiation Goggles PhotochemicalReaction Laser safety glasses: This type of goggles is a solution that infusesa specific chemical between two lenses. When the laser intensity exceeds acertain value, the color of the solution becomes darker, thereby blocking thelaser beam of a particular wavelength Too.

   Anti-laserradiation protection mirror discoloration glass-ceramic protective glasses: Theprotective lens is made of special glass or special plastic glass. Thesematerials are usually completely transparent, when the intensity of theincident laser light beyond the safety value immediately after the color, andthe laser absorption, light can still be restored after the transparent.Anti-laser radiation protection mirror High-

intensity Laser safety glasses: Itconsists of a planar mirror optical switch and a mirror, etc., can blockhigh-intensity laser radiation. The optical switch is a vapor-deposited polymerelement that has an absorbent property that protects against narrow-band laserradiation from visible to far-infrared, rather than a fixed spectrum. Itsprotective performance is related to the intensity of the beam, irrespective ofthe wavelength.

 Anti-laserradiation protection mirror aberration Laser safety glasses: This goggles areusually filled with water and alcohol between two layers of glass orcellophane, the use of Fourier transform principle to attenuate the laserintensity, to avoid laser damage to the retina, the protection wavelength cancover the entire Spectral range, without affecting the user's visualsensitivity.
