Red Color Glass Filter
Red Color Glass Filters use colored optical glass to transmit red light while absorbing selected shorter wavelengths. Spectral performance depends on the glass grade and thickness. Chenyu Optics supports drawing-based filter inquiries for imaging, sensing and optical instruments.
Red Color Glass Filter Overview
Red Color Glass Filters provide wavelength-selective transmission through absorption within colored optical glass.
These filters can be used for red-channel selection, contrast control and suppression of unwanted shorter-wavelength light. 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.

Red Color Glass Filter FAQ
What is a red color glass filter?
A red color glass filter is an absorptive optical element used to transmit red light and suppress selected shorter 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 red color glass filter block infrared light?
Do not assume infrared blocking from its red appearance. Some red filter glasses also transmit near-infrared light; check the selected glass spectrum.
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.
