Thanks for the answer. Apparently I don't really understand the diffraction optics. However what I am looking for is exactly what you describe however number of lines is not an issue for example, I can use 5 or 7 lines as long as the right most and left most lines are 6 degrees apart from the...

Hi All, For a project of mine I like to get custom make diffraction grating optical element to be built. I like this optical element to have 3 lines, with 6 degree half angle and 45 degree fan out angle. (i.e. angle between the center and side beams is 6 degrees) and 45 degrees along the...
