Hemispheric transmittance may be calculated as an integral over the directional transmittance described below. Spectral hemispherical transmittance in frequency

Thermal transmittance is the rate of transfer of heat through matter. The thermal transmittance of a material (such as insulation or concrete) or an assembly

Factor or Total Solar Energy Transmittance) is the coefficient commonly used in Europe to measure the solar energy transmittance of windows. Despite having

OSHA and ANSI regulate this technology, defining shades based on the transmittance of light. Welding helmets are most commonly used in arc welding processes

the fraction that is refracted into the second medium is called the transmittance (or transmissivity, or power transmission coefficient) T. Note that

are two types of binocular filters, classified by the shape of their transmittance curves. Tinted lenses (e.g. Pilestone/Colorlite/ColorMax glasses) apply
