Color Glass Filter
Color Glass Filters are optical components designed to transmit selected wavelength ranges while absorbing unwanted light outside the target spectrum. Using optical glass materials with controlled spectral properties, color glass filters provide stable transmission characteristics, effective light attenuation and reliable performance in imaging, sensing and optical measurement systems. Chenyu Optics manufactures color glass filters with custom materials, dimensions, thicknesses and spectral specifications for various optical applications.
Color Glass Filter Overview
Color Glass Filters are optical filters made from specially selected glass materials with controlled spectral absorption characteristics to transmit specific wavelength ranges while reducing unwanted light.
Using optical glass compositions with stable spectral properties, color glass filters provide reliable wavelength selection, light attenuation and broadband filtering performance. They are widely used in imaging systems, optical sensors, fluorescence equipment, machine vision and measurement instruments.
Chenyu Optics supports custom color glass filter manufacturing according to customer drawings, including different glass materials, dimensions, thicknesses, shapes and spectral requirements for prototype and repeat production.

Color Glass Filter FAQ
What is a color glass filter used for?
A color glass filter transmits a selected wavelength range while absorbing unwanted light outside that range.
What parameters define a color glass filter?
Key parameters include glass material, spectral range, thickness, transmission and surface quality.
How is a color glass filter different from a dielectric bandpass filter?
Color glass filters use absorptive glass materials for wavelength selection, while dielectric bandpass filters use thin-film coatings for narrower and sharper spectral control.
Can color glass filters be customized for different spectral ranges?
Yes. Filters can be customized using different glass materials for UV, visible, and near-infrared spectral ranges.
What information should I provide for a quotation?
Please provide spectral range, glass material, dimensions, thickness, quantity and drawing if available.
