What Is The Glass Lenses And The Resin Lenses?
Dec 25, 2017

  Optical lens is also called mirror heart, It is to the frame of the painting heart, suitable for clamping in the frame. Its form horizontal, vertical all can, is a kind of simple, convenient outfit type.

Classification: the optical lens can be divided into the following four categories according to the different materials: 

Glass lens of special lens for resin lens.

The main classification

: Glass lens

Glass lens: lens more scratch than other material properties, but its weight is heavy, the refractive index is relatively high: ordinary piece of 1.523 ultrathin section as follows: 1.72 above, up to 2.0.

Glass lenses are mainly made of optical glass. The refractive index is higher than the resin lens, so the glass lens is thinner than the resin lens in the same degree. Glass lenses have better transmittance and mechanical properties, with constant refractive index and stable physical and chemical properties. There are no color lenses called optically white (white)lens, and the pink ones in the colored films are called crocketed lenses (red). Crockett lens absorbs uv light and absorbs light.

The optical properties of glass are superior, not easy to cut, and high refractive index. The higher the refractive index, the thinner the lens. But the glass is fragile and the material is heavy.

Resin lens: resin is a kind of secretion from a variety of plants, especially conifers. Because of its special chemical structure and can be used for this latex paint and glue to be taken seriously. It is a mixture of various polymers, so there are different melting points. Resin can be divided into natural resin and synthetic resin. There are many kinds of resin, which are widely used in light industry and heavy industry, and can be seen in daily life. Resin lens is made from resin for chemical processing of raw materials.
