Solar glass light transmittance requirements

4 FAQs about Solar glass light transmittance requirements

What is visible light transmittance?

Visible Light Transmittance (Tv, %) is the percentage of incident light in the wavelength range of 380 nm to 780 nm that is transmitted by the glass. Visible Light Outdoors/Indoors (Re out/in, %) is the percentage of incident solar energy directly reflected by the glass.

What is visible light transmittance (VLT)?

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 100 (all light). This value measures the ability of the glass to transmit light and facilitate daylighting.

What is solar energy direct transmittance (Te)?

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 transmitted by the glass. Solar Direct Reflectance Outdoors/Indoors (Re out/in, %) is the percentage of incident solar energy directly reflected by the glass.

What is the difference between visible transmittance and visible reflectance?

Visible transmittance (τv) and visible reflectance (ρv) refer to the ratio of the beam of visible light vertically incident on a glass surface to the incident beam of transmitted light or reflected light.
