Absorbent,reflective Laser safety glasses excellent and inferior We knowthat the world is not the best products only better products, the followingXiaobian for you to understand the laser goggles of the two different styles ofadvantages and disadvantages. Absorbent, reflective laser goggles excellent andinferior.
Reflectivelaser goggles are coated with a multilayer reflective dielectric layer on thesurface of the base optical glass.
advantage:
1,the process is simple;
2,high visible light transmittance;
3,the attenuation rate is higher;
4,light reaction time fast 10-9 seconds;
Disadvantages:
1,the light source has a serious selectivity. The incident light source must beon the protective mirror (incident light mirror normal direction), theprotective effect was the largest, and vice versa;
2,reflective media layer easy to take off, and after the fall is not easy toobserve the naked eye, which is the most dangerous, the domestic reflectivemedium layer is about a year or so will fall off. The higher the lightattenuation rate, the thicker the dielectric layer, the easier it is to falloff.
Absorbentgoggles Add special wavelength absorbers to the base material PMMA or P.C.
advantage:
1,the light source is not selective, you can safely protect a variety of diffuselight;
2,the attenuation rate is high; 3, the surface is not afraid of wear and tear,even if there is scratched, does not affect the light of security;
4,light reaction faster 10-9 seconds;
Disadvantages:
Visiblelight transmittance is low.
