I have found the rectangular artifact is there with all the glass lenses I've tried even a 520nm AR coated 2 element lens. But it is worst with a single aspheric lens like the G-2. With that lens it really stands out. I have sent a couple of Sharp diodes to ElectricPlasma. Including one with the 495nm diode in it. Ask him if he sees the artifact with any of the builds I have sent him. They all had acrylic lenses on them.
