Measurement of Solar Transmittance through Plate Glass
In this example, several types of glass were measured using a UV-3600 UV-VIS-NIR spectrophotometer and their solar transmittance was calculated using solar transmittance
Key Glass Performance Measures
Visible light transmittance (VLT) is a percentage of the visible portion of the solar energy spectrum coming through the glass. It is expressed as a figure between 0 (no light) and
Performance value terms
Solar Energy Direct Transmittance (Te, %) is the percentage of incident solar energy in the wavelength range of 300 nm to 2500 nm that is directly
Solar control
Glass manages solar heat radiation by three mechanisms: reflectance, transmittance and absorptance. Absorptance – the proportion of solar radiation absorbed by the glass.
