Coated optical glass filter

Coated optical glass is a high-performance material that changes its optical properties through surface coating technology, and is widely used in fields such as electronic displays, automobiles, and optical instruments. Here are its core functions and application analysis: 1. Definition and classification Coated optical glass is a glass substrate coated with one or more layers of metal/dielectric thin films (such as ITO conductive film, anti reflective film, etc.), used to adjust the reflection, transmission, or polarization characteristics of light,Specific spectral characteristics. 2. The main types include: Heat reflective glass: reduces infrared transmission and is used for building energy efficiency. Low-E glass: balances transparency and insulation, commonly found in automobiles and buildings. Conductive film glass: such as ITO conductive glass, used for touch screens and display devices. 3. Core processing techniques and technologies Surface vacuum plating: Deposition of n…
