This report represents authors's suggestions on describing the Veiling Glare(VG)characteristic of the microscope objectives by Veiling Glare Index(VGI)and Charaterized Veiling Glare Index(VGI(NA
c
)
which have been proposed on the base of the measurements of a large number of various microscope objectives by using the instrument for testing the VGI of microobjectives developed in the Institute.Furthermore
the report introduces our experiments and discussions about the influence of those variable parameters in the testing instrument
such as the limiting aperture of the black object target
defocus and etc.
on the testing results.At last this paper gives our suggestions for the standardization of the measurement and assessment of the VG characteristics of microscope objectives.
