I got a chance to play with some of the optics out of my sequencer last night. One of the coolest ones is something called a "long Pass Edge Filter." This one is a "532 EFLP" When you shine the multi-line argon at right angles to the filter, it reflects 100%. As you turn it though, magic happens . . . .
As you turn it the filter begins to split the beam about 50-50. However, what is split is too cool. At the first, the green line is passed and the violet line is reflected. As you continue to turn it the colors go through a gradual shift through the color lines until at the farthest angle the violet line is being passed and the green line is being reflected!! This shift happens smoothly and gradually. You can make the beams any color gradient you desire all along the color range of the tube. It is NOT broken up discretely like when the beam is reflected off of or shined through a grate. It is smooth and gradual.
If you have a multi-line argon, get yourself one of these filters.
Peace,
