Preparation process and coloring mechanism of colored optical glass
The preparation process of colored optical glass is similar to that of colorless optical glass, but the requirements for its spectral characteristics are lower. The coloring mechanism mainly includes ion coloring, metal colloid coloring, and sulfide selenium compound coloring. Rare earth elements such as cerium and neodymium are commonly used for coloring, achieving specific color effects by changing the transmittance or adjusting the refractive index.
Historical background and development trend
The history of colored optical glass can be traced back to early research and application of optical materials. With the development of technology, colored optical glass is becoming increasingly widely used in fields such as color photography, night vision equipment, and laser technology. In the future, with the advancement of new materials and preparation technologies, the performance and application scope of colored optical glass will be further expanded.
In short, colored optical glass, as an important filtering material, not only has a wide range of applications in the field of optics, but also plays an indispensable role in modern technology.
