The CIE 1931 and CIE 1975 LAB are Human Perceiveable Color. Later in 1993 the CIE Standard - International Color Consortum (ICC) became Human Percieveable Color in CRT - TV Space for the purpose of printing to a press.
If you notice from the test the Color Temp is based on 5000K (Color Temp is Red - Not equal Energy) and in addition this is based on the later 1993 ICC "TV" LAB Standard
I think this test is interesting... though I think a better test would be a run down of each lens seperate, prism system and then the whole system as a total.
I would also like to know the description of the light source. (Focus, flood, etc..) My company actually builds PMT Devices and this matters alot.
The sentence which says: "The optical alignment of the binocular with respect to the measurement systems's optical axis is directly related to measurement uncertainty. Makes me wonder how valid the test really was..
In any case.. glad someone is trying to get greater detail on bino performance.
