I love using a fiber lens on color holography, it make the beam mixing so easy and very clean, and even with the hene I get a good coherence as long as the beams go threw the center of the lens, I have 2 fiber lens one small and one twice as big..the bigger one the fibers are really fine that you can't see the fibers , the beam size I use is 1 cm
