What is Heat Absorbing Float Glass?


Heat Absorbing Float Glass (HAFG) is designed with the capability to typically absorb 40% of the infrared (IR) light and about 25% or more of the visible light that passes through it. The glass reduces solar heat while maintaining visible light transmission. The soda lime glass is a light blue/green color which subdues brightness while providing high visible light transmittance of up to 77% for a glass that is 6.0mm thick. Heat absorbing float glass is often used as a shortpass (SP) filter.


A shortpass filter is an optical interference or colored glass filter that attenuates longer wavelengths and transmits or passes shorter wavelengths over the active range of the target spectrum (usually UV ultraviolet and visible region). Learn More


Common uses include fluorescence microscopy and in dichromatic mirrors and excitation filters.
