Diffuse incident light
With diffuse incident light, the light does not come from a clearly identifiable direction but is emitted from a large area. This can be achieved by using a diffuser (frosted glass pane) in front of a direct incident light and/or by using large surfaces. Other diffuse incident lights are coaxial lighting, dome lighting and tunnel lighting. Diffuse incident lights are particularly suitable for shiny, metallic and slightly uneven objects.
A uniformly structured surface, for example metal with a certain roughness, appears almost uniformly bright due to the diffuse reflection from the surface structure. Significant indentations such as scratches and elevations, on the other hand, lead to different reflection angles and shading, resulting in a clear contrast to the surface.
Büchner offers a large selection of surface lighting and backlighting.
