Optical glass material, advantages: high light transmittance (97%), high temperature resistance, etc.; disadvantages: single shape, fragile, difficult to achieve mass production, low production efficiency, high cost, etc. However, at present, very few domestic manufacturers have begun to develop glass molding technology, using mold fusion casting to produce glass lenses, which can produce lenses with various shapes and special surfaces.Our company kinglux glass lens is at the forefront in this regard.

In addition, mold production, product consistency, high precision, and can greatly improve production efficiency, effectively reduce the cost of glass lenses, coupled with the characteristics of high light transmittance, glass lenses are bound to become optical plastic high-power LED Alternative products for lenses. However, the current high price of such production equipment makes it difficult to popularize in the short term. In addition, the shortcomings of glass that are more fragile than PMMA and PC materials require more research and exploration. In terms of the improved technology that can be achieved now, the non-fragile characteristics of glass can only be improved by coating or tempering, although these treatments , The light transmittance of the glass lens will be reduced, but it will still be far greater than the light transmittance of ordinary optical plastic lenses. Therefore, the prospect of glass lenses will be broader.
