Life has never been short of ideas, but notmany unique material shortage of research and application, so we shouldunderstand clearly that we never stop in the day about the diversification ofmaterial use. In our glasses looks like we are not unfamiliar with the needlemust on the characteristics of laser applications, practice days to a greatextent to help us deal with laser very much doubt, redefined many traditionalinefficient operation. Laser is really a good thing, but we have to understandthat it is precisely because of the laser we have also formed a lot of damageto the environment itself.
First,it is concluded that the choice of grade laser glasses. Laser protectivegoggles are generally divided into two categories of imports and domestic. Inaccordance with the certification can be divided into CE certification (CECertiED) and the identification of the goods, in accordance with the level ofprotection can be divided into OD1+ to OD7+ grade, with reference to"laser glasses safety grade and the standard". On most use, werecommend using CE certified products, and introduced the selection of thehighest level of protection OD7+ goods. Of course, we also need to see moreabout the protection level parameters for some ultrafast lasers, such as FSlasers.
Two, according to the operating conditions,the laser protection of the visible light transmittance requirements. Becausethe laser protective mirror has a good protective effect on the laser, it canalso block some visible light. Most users expect to achieve a higher visiblelight transmittance, such as VLT>50%, it is easy to direct investigation oflaser experimental fantasy or laser machining process, without the need forother auxiliary light source; a few users request the lower visible lighttransmittance, such as visible light is too strong in some situations, the typeof <50%, and the transmittance of referrals <30%, with the best effect toprotect the eyes.
Lasers are now the most widely used andmost widely used element in our days. We can use the laser material in the dayis not just a simple easy, laser may in many people's heard are relativelysimple and safe use, the practice is not the case, if we are in the process ofusing laser material presents questions that will be very simple for our ownformation damage the damage, and this damage is still the laser material toform irreversible, once we have laser damage, almost can not be restored.
