Definition and Characteristics
Colored optical glass is made by adding colorants (such as metal oxides, rare earth metals, etc.) to change the color of the glass while maintaining its optical properties. This type of glass has selective absorption and transmission properties for specific wavelengths of light (visible light, ultraviolet light, or infrared light), and is therefore also known as filter glass
Types and Applications
Red colored optical glass: mainly used to reduce yellow light components, enhance display brightness and contrast, commonly used in mobile phone camera lenses, color filters, etc.
Green colored optical glass: It has good infrared transmittance and is suitable for fields such as night vision goggles and infrared cameras.
Blue colored optical glass: used in the manufacturing of optical devices such as spectrometers, lasers, LEDs, etc., to help eliminate aerosol phenomena.
Yellow colored optical glass: used in the field of lighting to prevent ultraviolet radiation and provide sufficient brightness and brightness.
Purple, brown, gray and other colored optical glass: These colors of glass also have their specific application industries, such as purple and brown glass commonly used for decoration and special optical equipment
