Laser protective glasses with you to understand the laser standards and classification

   To ensure that the eyes will not suffer theinfluence of laser, want your eyes to get useful in maintaining contact laserwork, please come to our selection of laser protective glasses, is useful tohelp more people to prevent the laser damage of laser protective glasses, thentogether with small to understand the laser protective glasses andspecification detailed classification specification and classification of laserlaser protective glasses

    1 American laser safety specificationZ136.1 ANSI: after the optical density (OD, Density Optical) to measure, theoptical density of OD and the transmission ratio of the logical relationshipbetween T: T D=-log10.

    2 European laser safety specificationEN207/EN208: thinking about the optical density of OD, in addition to the needto think about the damage threshold.

    According to the American laser safetyspecification Z136.1 ANSI and the European laser safety specificationEN207/EN208, the laser can be classified as follows. ClassDefinitionSuggestion

   1 there is no risk of 1M eye safe laser(400-700nm) without laser protection, without optical enlargement without laserprotection.

   2 eyes visible laser safety (400-700nm),0.25 seconds to blink visible laser safety without laser protective glassesbinocular 2M security (400-700nm), 0.25 seconds to blink safe, with opticalexpand advocate the use of protective glasses 3R direct laser may not be safe,visible in some 5 times the 2 level laser, in the invisible some light is 1level laser 5 times advocated the use of protective glasses

   3 look at the laser is not safe, diffusereflection laser to prevent the use of protective glasses as far as possible

   Type selection of laser protective glasses

   1 laser characteristics: laser outputwavelength, power density.

   2 optical density Density Optical (OD):ODnumerical value is greater, the more the protection of laser protective glassescan be.

   3 visible light transmission rate LightTransmittance Visible (VLT):VLT value less than 20%, the need for the use ofoutstanding lighting environment.

   4 frame Frame: whether or not to wearglasses, facial contour, the above is small as we supply information, is alsothe use of laser protective glasses in contrast widely, not the same area theuse of glasses is not the same, so we recommend especially in this small seriescan be applied laser protective glasses to ensure the maintenance of our. Inthe eyes of laser protective glasses useful, thank you together has paidattention to our old customers, for our trust!
