What are the advantages of optical glass? Let’s find out together with Dongsheng Optoelectronics, a manufacturer of optical lenses. Optical glass can alter the direction of light propagation and modify the relative spectral distribution of ultraviolet, visible, or infrared light. At high refractive indices, optical glass exhibits a low dispersion coefficient, good hardness, easy coloration, and excellent light transmission; it also allows for thinner lens profiles, provides UV protection, and is well-suited for full‑rim eyeglasses. The refractive index of glass lenses typically ranges from 1.7 to 1.89. (1) Optical glass boasts high transmittance, reaching up to 92%. If one or more layers of magnesium fluoride anti‑reflection coatings are applied to the lens surface, the transmittance can be increased to as much as 99%.

(1) Optical glass has high transmittance, with a transmittance of up to 92%. If one or more layers of magnesium fluoride antireflection coating are applied to the lens surface, the lens’s transmittance can reach 99.2%.

 

 

 

(2) Optical glass absorbs ultraviolet radiation, thereby preventing UV‑induced damage to the eyes.

 

 

 

(3) Optical glass exhibits chemical stability and is resistant to corrosion by acids, alkalis, and other chemical substances.

 

 

 

(4) Optical glass has a constant and precise refractive index of 1.523. , stable and accurate, with precise post-processing refractive power.
