Blue Color Glass Filter
Blue Color Glass Filters use colored optical glass to transmit blue light while absorbing selected unwanted wavelengths. Spectral performance depends on the glass grade and thickness. Chenyu Optics supports drawing-based filter inquiries for imaging, sensing and optical instruments.
Blue Color Glass Filter Overview
Blue Color Glass Filters provide wavelength-selective transmission through absorption within colored optical glass.
These filters can be used for blue-channel selection, contrast control and suppression of unwanted wavelengths outside the required blue transmission band. Select the glass grade using the required transmission curve.
Send Chenyu Optics your drawing, target spectrum, glass grade and thickness for manufacturing review. Dimensions, surface finish and coating requirements should be agreed before production.
Key Advantages of Blue Color Glass Filter

Blue Color Glass Filter FAQ
What is a blue color glass filter?
A blue color glass filter is an absorptive optical element used to transmit blue light and suppress selected unwanted wavelengths.
What determines the transmission curve?
The glass grade and thickness determine the spectral response. Specify the required transmission and blocking at the wavelengths relevant to your application.
Does a blue color glass filter block infrared light?
Infrared blocking depends on the glass grade and thickness. A blue appearance alone does not define the infrared response; check the full transmission curve against your detector range.
Is a coating required for color filtering?
Color filtering is provided by the glass itself. Additional surface coatings should be specified separately if needed.
Can I request custom dimensions?
Send your required dimensions, thickness, tolerances and surface specifications to Chenyu Optics for manufacturing review.
What information should I provide for a quotation?
Please provide the target transmission curve or glass grade, thickness, dimensions, surface requirements, quantity and drawing if available.
