余弦矫正器
余弦校正器是一种光学漫射体,用于收集180度立体角内的光。余弦校正器的表面根据朗伯体余弦定律响应:落在余弦校正器上的光量与光束入射角的余弦值成正比。
在60度角时,仅测量一半辐射强度,而在0度角时测量100%。余弦校正器的一个典型应用是照明情况的照度测量。
How are you measuring?
With fibers and other accessories even more type of measurements are possible. Often used accessories are integrating spheres, cuvettes for fluids, light sources or filter holders.
A cosine corrector collects the light from the half space under 180 degrees. A typical application is the illuminance measurement of a lighting situation.
Consumers are used to enjoy top-quality displays in their mobile phones, tablets, laptops and even cars. Emerging technologies such as lighting surfaces for office and home illumination are expected to look equally perfect. Both displays and luminous surfaces are the main application areas for imaging colorimeters.
Measuring the luminance or color values at a specific location of the device under test is a typical use case when measuring displays. It can, however, also be meaningful to assess reflected light.
