TīmeklisLambertian emitter. Lambertian emitters are isotropic over the half-sphere. They are seen having the same luminance from any direction. However, the emitted radiance will depend on incidence due to the cosine projection factor from the radiative transfer equations. A base light emission spectrum, setting dependence of radiance to … Lambertian reflectance is the property that defines an ideal "matte" or diffusely reflecting surface. The apparent brightness of a Lambertian surface to an observer is the same regardless of the observer's angle of view. More technically, the surface's luminance is isotropic, and the luminous intensity obeys Lambert's cosine law. Lambertian reflectance is named after Johann Heinrich Lambert, who introduced the concept of perfect diffusion in his 1760 book Photometria.
