Let me introduce you: What are the advantages of optical lenses?

Optical glass can change the direction of light propagation and can change the relative spectral distribution of ultraviolet, visible or infrared light. Optical glass has a low dispersion coefficient at a high refractive index, good hardness, easy staining, good light transmission, the lens is matched with a thin contrast, anti-ultraviolet, suitable for full-frame glasses, the refractive index of the glass lens is 1.7-1.89.

What are the advantages of optical glass? Following the optical lens manufacturer Haosheng photoelectric take a look together.

(1) High optical glass transmittance, transmittance of up to 92%, if on the lens surface plated with a layer or multiple layers of magnesium fluoride anti-reflection film, lens transmittance of up to 99.2%.

(2) Optical glass absorbs ultraviolet light to avoid ultraviolet damage to the eye.

(3) Optical glass chemical stability, acid, alkali and other chemical substances corrosion resistance.

(4) The refractive index of optical glass is constant and accurate, the refractive index is 1.523, constant and accurate, and the diopter is accurate after processing.
