lightpermeability
Lightpermeability is the property of a material or medium that describes how easily light can pass through it. It is commonly expressed as transmittance, the ratio of transmitted to incident light, and it typically depends on wavelength. Materials with high lightpermeability are considered transparent, while those with low lightpermeability are opaque; intermediate values describe translucence.
Measurement of lightpermeability is often carried out with spectrophotometric methods. Transmittance T(λ) is measured across wavelengths
Several factors influence lightpermeability. Sample thickness, the intrinsic absorption coefficient α(λ), and the scattering coefficient μs(λ) play
Applications and examples vary widely. Clear glass and many polymers have high visible lightpermeability, suitable for
Related concepts include transparency, translucence, and optical density. Designers and researchers tune lightpermeability through composition, thickness,
