IdealPhotonics' scattering sheet is an optical element that uses surface microstructures or internal inhomogeneities to induce directional scattering or diffuse reflection of incident light. Its core function is to disrupt the spatial coherence of light, transforming a collimated beam into a uniformly diffused light field.Through precise microstructure design on its surface or within the structure, incident light can be controllably converted into a uniformly scattered light field with a specific angular distribution, while simultaneously balancing transmittance, haze, and scattering uniformity.
