Hi Alaskan,
It is a good suggestion. In this way I can find use of that NON-polarizing beamsplitter, aliexpress seller sent to me instead of the ordered one. I only need to check if it exactly reflects 50%. And with 3 of those half-mirrors in a row it will be possible to "increase LPM slimit" 8 times!
And since they will reflect excess of light by side and not absorb it, the calculation would be easier than in case of glass filter with unknown opacity, where transparence may change at heating while light is absorbed.
Now I know what NON polarising beamsplitters are useful for!
