本文描述了一个测光系统的设计，使没有不合理的假设，并有一个强大的视觉联系。它跨越明视觉、中间视觉和暗视觉区域，并且基于与10度视野匹配的亮度，中心固定。英国国家物理实验室对三色仪进行了深入的研究，加拿大国家研究理事会利用更多的观察者对三色仪进行了广泛的研究。一个二分场允许9个观察者中的每一个对孔径颜色进行相等的亮度设置。测试的刺激光谱和非光谱和数据被用来推导公式，用户可以采用。通过插入刺激（其可以例如是光源）的常规光度量，用户可以获得其对应的光度值，无论其是明视的、中间视的还是暗视的。
This paper describes a system of photometry designed to make no unjustifiable assumptions, and to have a strong visual linkage. It spans the photopic, mesopic, and scotopic regions and is based on brightness matching a 10-degree field, centrally fixated. An intensive investigation was made on the trichromator at the National Physical Laboratory, Great Britain, and an extensive one, using a greater number of observers, on the trichromator at the National Research Council, Canada. A bipartite field allowed equal brightness settings of the aperture colour by each of nine observers. The stimuli tested were both spectral and nonspectral and the data were used to derive formulae which a user could employ. From inserting conventional photometric quantities of a stimulus, which might for example be a light source, the user can obtain its corresponding photometric value whether it be photopic, mesopic, or scotopic.
