Optical glass is made of high purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium oxide in a particular formula mix, high temperature melting in the platinum crucible, stir well with ultrasonic, to bubble; Then after a long period of time slowly cooling, lest produce internal stress in the glass block. After cooling the glass block, must go through optical instrument measurement, test of purity, transparency, uniformity, refractive index and dispersion rate is standard. Qualified glass block after heating forging, MAO embryo into optical lens. And then processed into qualified optical lens. Optical lenses when use should pay attention to these points: 1, the need to wear gloves when using, have easy corrosion on the surface of the glass material such as acid, salt, if direct contact lenses with the hand, can lead to optical lenses to produce imprinting, if long time not to wear, may become a permanent spot printing, affect the imaging quality of optical elements. 2, need not when, should be placed in the surface of the soft, can not directly put the bare chip on glass, metal, desktop or not clean paper, this lens is very easy to scratch. 3, if there are any lenses have a couple of dust on the surface, with a clean wash ears ball a few times, blowing the dust blown away. 4, light with light, optical lenses are glass products, easy bruising, side damage, scratches, take the edge of the lens, not to direct contact with the pervious to light, even wear gloves have no direct contact. 5, preservation, want to wipe with clean paper capacitance or lens paper, should be put in moderate temperature ( It is advisable to 23 ℃ or so) , humidity, Less than 40%) Environment, conditional word in the drying cabinet. 6, once found optical lens is dirty, clean them immediately, but should pay attention to prevent scratches, dust make lens scratches very easily.
