Thanks again sophiecentaur I will improve the actual system by trying to focus much of the light to the slit. I have to dig in in more into optics. A condenser lens is a good idea to make the light beams more parallel, than when they go through cylindrical lens the focused light will be...

Thanks. I've put tracing paper on the slit to avoid this problem, but I want to try diffused glass plate to have more light on the slit...if I continue with this setup.

Thanks sophiecentaur for the detailed feedback. The handmade resin lens will work only with the setup in the picture -> focusing much of the light on the slit. In this case the flare is not a problem. The end of the lines don't have to be perfect, what is important to project this line from 1-4...

Thanks for the ideas, they are all good! White would be good, but colored ones can be an option as well. I just have to see if these layers are harmful to human eyes. This could be an option, than I don't have to use camera lens. I will cast resin lens (the glass ones are expensive). Here the...
