Optical agglutination lens is the most commonly used optical material, its mature manufacturing technology, complete varieties.
General optical agglutination lenses can through the wavelength is
In the production and life a lot of a lot of need to use glass lenses, but you can distinguish between optical lenses bonding and ordinary lens?
Let's together to learn about: common glass: has nothing to do with chemical composition and the curing temperature area, they through supercooled melt method, due to the increase of viscosity with the mechanical properties of solid, and from a liquid to a glassy state transition process is reversible.
Optical agglutination lens 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, go to the 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.
Optical lenses bonding and ordinary lens of the main difference is that: optical agglutination lenses with high transparency, physical and chemical properties of high uniformity and optical constants that are specific and precise.
The performance is ordinary lens can't replace.
In today's rapid development of science and technology, a new optical material resin lens, regardless of its optical performance, safety performance, to prevent harmful rays eye protection performance is far better than ordinary glasses.
