How about the refractive index of china textured glass
China textured glass is very common in our daily life, such as full-length mirrors, cosmetic mirrors, etc., so how about the refractive index of China textured glass? The editor of this article will reveal it with you.
China textured glass is more scratch-resistant than lenses made of other materials, but its weight is relatively heavy, and its refractive index is relatively high: 1.523 for ordinary lenses, and above 1.72 for ultra-thin lenses, up to 2.0.
The main raw material of china textured glass is optical glass. Its refractive index is higher than that of resin lenses, so under the same degree of power, glass lenses are thinner than resin lenses. The light transmittance and mechanical and chemical properties of glass lenses are relatively good, with a constant refractive index and stable physical and chemical properties. The lens without color is called optical white support (white lens), and the pink lens in the colored lens is called Crocker lens (red lens). Croxel lenses can absorb ultraviolet rays and have a slight absorption effect on strong light.
China textured glass has superior optical properties, is not easy to scratch, and has a high refractive index. The higher the refractive index, the thinner the lens. However, the glass sheet is fragile and the material is heavy.
