Leneta Test Charts

Opacity Charts

The term “Opacity Chart”, as used in this catalogue, refers to charts on which the test pattern is a simple combination of black and white areas, large enough for wide aperture reflectance instruments, as well as for visual opacity and colour observations. Leneta opacity charts comply with all test methods specifying charts of such design.
