Laser Protective Glasses Features:
A.Absorbent protection, even if there is a scratch, it will not affect the protection effect;
B.The lenses are hardened and strengthened to prevent impact, scratches, explosion and scalding;
C.The optical density is higher, the attenuation rate is higher, and the protection is more efficient and reliable
D.The visible light transmittance is high, which increases the operability and comfort of the wearer;
E.Various styles and designs, suitable for users with various face shapes, head shapes and different needs
F.It has good shielding to the dazzling white light generated in the operation of the laser.
Purchase Tips:
(A).What are the types of protective goggles?
Answer: The protective glasses on the market are divided into reflective protective glasses and absorptive protective glasses. Protective protective glasses are embodied by coating the surface of glasses with a reflective film; absorptive ones are embodied by adding laser absorbent into the lens material and testing the entire lens. Absorb the laser to achieve the protective effect.
(B).What are the characteristics of each type?
Answer: Reflective goggles are easy to operate and low in cost, so the unit price is relatively low. However, if there is any damage to the reflective film, the protective effect of the glasses will be greatly reduced; the absorptive type needs to ensure the absorbent and base bottom because the process is more complicated. The uniform fusion of materials generally has a higher unit price, but any scratches will not affect the protective effect.
(C).Are there any absorbent protective goggles with a relatively low unit price?
Answer: Nowadays, after repeated use of an absorbent, the absorption effect will rapidly decay due to the saturation of the absorbent’s performance. This type of absorbent has a low production cost, so it can ensure that the unit price of the protective glasses is low, but it must be noted that for long-term For workers exposed to lasers, this type of protective goggles is difficult to ensure long-term effective protection of their eyes.
(D).How to choose the right protective goggles?
Answer: Determine the protection band-compare the absorption coefficient (OD) of this band-contrast the light transmittance (VLT)-select the type of protection (reflection/absorption)-pay attention to the service life-choose the style to place an order.
OD: the multiple of attenuation after light is absorbed (10ʌn) OD=1 means 1/10 OD=2 means 1/100 VLT: The transmittance of visible light, expressed as the clarity of wearing glasses to see objects other than the laser.
