Hajäisäteilymateriaali

Hajäisäteilymateriaali, also known as scatterometry material or diffusion material, refers to materials designed to scatter or diffuse light or other electromagnetic radiation. These materials are employed when it is desirable to spread incident radiation over a wider area, reduce glare, or create a uniform light distribution. Common applications include displays, lighting fixtures, and optical sensors.

The scattering effect is typically achieved through microscopic surface textures or internal structures within the material. These irregularities cause incident radiation to deviate from its original path, resulting in diffuse reflection or transmission. The degree of scattering can be controlled by the size, shape, and distribution of these features. Materials used for this purpose can range from plastics and polymers with embedded particles to specially treated glass or films.

In display technology, hajäisäteilymateriaali is often used as a diffuser layer in LCD screens to ensure even backlighting. In lighting, it can soften the harshness of direct light sources, creating a more pleasant and ambient illumination. In optical systems, it might be used to homogenize light beams or to create specific optical effects. The performance of hajäisäteilymateriaali is often characterized by its haze value, which quantifies the degree of light scattering.
