lambertian | - Having a surface that reflects light diffusely and uniformly rather than specularly. see matte. most objects have a lambertian surface. compare specular.
- Having a surface that reflects light or acoustic energy diffusely in all directions rather than specularly. see also matte. compare specular.

lambertian emitter | An emitter that radiates according to lambert’s cosine law, which states that the radiance of certain idealized surfaces depends on the viewing angle of the surface. the radiant intensity of such a surface is maximum normal to the surface and decreases in proportion to the cosine of the angle from the normal. given by: | |
lambertian source or surface | - A surface is called a lambert radiator or reflector (depending
- A surface is called a lambert radiator or reflector (depending whether the surface is a primary or a secondary source of light) if it is a perfectly diffusing surface.
| |
lambertian surface | An ideal diffuse surface whose emitted or reflected radiance (brightness) is dependent on the viewing angle. |
