Luminance meter
Appearance
A luminance meter is a device used in photometry that can measure the luminance[1] in a particular direction and with a particular solid angle. The simplest devices measure the luminance in a single direction while imaging luminance meters measure luminance in a way similar to the way a digital camera records color images.
