Description

Luminance standards and radiance standards are used in photometry and radiometry, in particular for the calibration and characterization of cameras and optical measuring devices. Another application is the determination of reflection, transmission and absorption properties of materials. Luminance and radiance standards are homogeneous light sources that have a uniform brightness over their entire emitting surface and emit almost perfectly lambent and uniformly in all directions. The mode of operation is based on the principle of the integrating sphere. The integrating sphere consists of a hollow, spherical structure with a highly reflective inner surface. This surface is coated with a diffuse reflective coating of barium sulphate, which scatters almost 100% of the incident light. This property enables the sphere to distribute the light evenly in all directions and eliminate directional effects.
