But for 80% absorption or less you may not even need a power meter - this kind of transparency can be checked with much easier and cheaper methods, e.g.:
- Display an area of pure green somewhere on your monitor (pure green means RGB=255/255/255 or HSL=85/255/128)
[...]
That was, of course, wrong - pure green at full saturation and half luminance is RGB=0/255/0. The rest was right.
