Expanding green ?

[polishedball]

Since I use my lasers for home use and total throw distance is 12~20' depending on the room I am fine with my fat red and blue stripe. While i'll experiment to reduce and improve them I am wondering if my best look would be easier accomplished by degrading the green beam. Right now my yellows have the red outline and some colors have blue outline. With blue and red about the same size and acceptable for my use is what would be the best way to expand the green beam? This may give me the best look. Also the blue could use expansion some on one axis. Just wondering what it take to try. Thanks

Buy two 25 mm focal length lenses with AR coats. 50 mm apart = unity, anything other then that = expansion.

Or buy a 25 and a 50, etc.
