Heat Absorbing Glass Filter
Heat Absorbing Glass Filters transmit visible light while absorbing infrared radiation within the selected glass absorption band. Performance depends on glass grade and thickness. Chenyu Optics supports drawing-based inquiries for illumination and optical instrumentation.
Heat Absorbing Glass Filter Overview
Heat Absorbing Glass Filters combine visible-light transmission with infrared absorption within optical glass.
Select the glass grade and thickness using the required transmission curve. The absorbed energy heats the filter, so source power, mounting and cooling conditions should also be reviewed.
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.

Heat Absorbing Glass Filter FAQ
What is a heat absorbing glass filter?
A heat absorbing glass filter transmits visible light while absorbing infrared radiation within the selected glass absorption band.
What determines the transmission curve?
Glass grade and thickness determine the spectral response. Specify the required transmission and attenuation at the wavelengths relevant to your application.
Does a heat absorbing glass filter block all infrared light?
No. Infrared attenuation varies with wavelength, glass grade and thickness. Check the full transmission curve against your source spectrum.
Does the filter itself become hot?
Yes. Absorbed radiation heats the glass. Source power, exposure time, mounting and cooling must be considered when selecting the filter.
Is a coating required for heat absorption?
Infrared absorption is provided by the glass itself. Additional surface coatings can be specified separately and reviewed for compatibility.
What information should I provide for a quotation?
Please provide the target spectrum or glass grade, dimensions, thickness, tolerances, source power, mounting conditions, surface requirements, quantity and drawing if available.
