It is important to choose a suitable laserprotective glasses, in different working environment we need to wear glasses isnot the same, trust using laser protective glasses friends all know the effectof laser protective glasses, wear in use in laser operating environment isreinforced for eye protection, prevent the influence of laser, so want tochoose a suitable laser protective glasses, is our preferred laser antiprotective glasses.
Laser protection glasses have a variety oftypes, the information is not the same, the principle of different, the use ofoccasions are not the same. Laser protective glasses are worn in the laseroperating environment, in a non operating environment, wear will be a littlenot to adapt to the feelings, long time to adapt to the. Laser protectiveglasses are useful for laser protection, must be in accordance with thedetailed application of the request for a reasonable selection of laserprotective glasses. Choose the door mirror, the maximum laser output power ofthe primary basis (or energy), beam diameter, laser pulse time parametersdetermine the maximum output irradiance or maximum exposure. Then, according tothe maximum allowable exposure time (corresponding wavelength and shining eyesshine limits) concluded that glasses the minimum optical density value, andthen select the appropriate protective glasses.
Details of the selection are mainly:
1, the maximum amount of radiation Hmax(J/m2) Emax (W/m2) or the maximum irradiance;
2, specific protection wavelength;
3, the optical density value of Dmin to thecorresponding protective wavelength;
4, the non - uniformity of the protectivelens, non - symmetry, the incident light point of view effect, etc.;
5, anti laser radiation ability;
6, visible light transmittance;
7, structure and shape. The use of Chinesefor laser safety mandatory standard: CJB-2408-95 laser protective glasses protectionfunction test method of laser protective glasses health protection GJB-1762-93request JB/T 5524-91 laboratory laser safety rules, laser protective glassesour company produces, applicable to all kinds of laser wavelengths andprotection (266nm-----532nm----1064nm----10600nm), the optical securityfunctions completely satisfied GJB1762-93 "laser goggles physical healthstandard", all functions and scale with the physiological characteristicsof China norms and human satisfaction request, fit most people wear.
Wear protective glasses is a laser toprotect the eyes from laser operation in the operation, so in the sameenvironment we use glasses is not the same, you pick the right glasses? Laserprotection homework you ready? The above is small as we supply some for laserprotection glasses of common sense, hope to be able to bring you to help
