Laser protective glasses part of knowledge

   The use of the scientific development oflaser today a lot, but there are many people using laser protective goggles.Because people are aware of the laser is harmful to people's eyes. Knowledgeabout the laser protective goggles from the article.

   Laser protective glasses is composed ofpolycarbonate (PC) and the Australian industry imports of certain wavelengthsof light absorption materials synthesized a kind of efficient explosion-proofsafety goggles. PC lens light weight, good toughness, not broken, is widelyrecommended by international ideal safety glasses. The optical safetyperformance fully meet GJB1762-93 "laser protective goggles physicalhealth standard".

   : protective wavelength of 532 nm, 532 nm,650 nm, 660 nm, 780 nm, 808 nm, 850 nm, 980 nm, 1064 nm, 10600 nm, a optimalphotoelectric technology co., LTD. Beijing has laser protective glasses wearingcomfortable, beautiful, safe and reliable. Laser protective glasses using lightabsorption principle: its no selectivity to light source, safe protection canbe all kinds of diffuse light; In light of the incident Angle selectivity, noAngle of incident light have been equally efficient protection. Specificwavelength of laser and light can be all-round protection. Light reactionquickly. The attenuation rate is higher. Surface is not afraid to wear, evenwith brush strokes, also does not affect the safety of light.

Usenotice:

   1, even to wear protective glasses can't faceup to laser light source.

   2, laser protective glasses for polymermaterials, rowing, grinding surface are strictly forbidden to hard objects.Clean the lens please use neutral detergent and water, clean water, then usethe glasses cloth to wipe clean. Eyes are most sensitive to the laser organs.Due to the nature of the laser, can make the energy concentration in space andtime.

   Due to eye lens has focused on the role ofthe retina by laser irradiation on unit area energy (power), higher than thatof the corresponding amount of corneal incident for nearly 100000 times. Goodmonochromaticity, laser in the fundus of the color difference is small. Becausepulse laser injuries far more quickly than the blink reflex (eye blink reflextime usually is 150-250 ms, and can short laser pulse to 10-6 S even 10-12s-class).

   Plus in a very short moment, on a tinyarea, the concentration of energy released, so that even low doses of cornea orretina caused by laser irradiation can also be serious damage. Damage iscumulative and laser to human eyes, not obvious at first, after now it is toolate. Therefore, protection from now on, don't forget! Beijing one optimalphotoelectric technology co., LTD. Is an enterprise specializing in theproduction of laser protection eyes. And many, many different kinds of laserprotective glasses, so you in laser operation, that is about to consider whatkind of safety glasses is most suitable for use!
