Yes, the 1.2W diode is in a pen. For now.Very nice collection, Pierce. Surely that 638nm 1.2 watt isn't in a chrome pen, is it? I saw your thread on using round cyl lenses to correct the divergence. It is almost square. Great rainbow shot. :thanks:
I haven't gotten around to correcting the beam but I'm working on some designs and thinking about the problems. I may not use corrective optics in the end and instead opt for a long focal-length lens.
