The light filtering fabric filters the passage of light. The optical values are defined according to European standard EN 14501.
Optical factors according to EN 14501
Visible light transmittance (Tv)
This is the total percentage of light radiation wavelength ranging from 380 to 780 nm (nanometers), called the visible spectrum, passing through the fabric.
Visible light reflection (Rv)
This is the percentage of light radiation reflected by the fabric.
Light Absorption (Av)
This is the percentage of light rays absorbed by the fabric.
A light filtering textile is a fabric that filters light. A portion of visible light waves is thus either absorbed or reflected by the fabric. The more light is filtered the more light transmittance (Tv) is low. A zero light transmission means that the fabric is blackout.
Light filtering fabric's properties:
- Light filtering
Our light filterling fabrics are particularly recommended for professional spaces, meeting rooms, offices...
Our light filtering fabrics are also M1 flame retardant.
