Hard to say what the divergence is considering the bad beam profile, but its 2.5 or greater depending on how it feels. beam at the aperture is about 1.5mm x 3mm all the time and hits the side of the lens creating some splash as well.
Who can you rely on for a quality laser these days?
Received my Spartan 532 series 300mw in a timely manner. Got it yesterday and haven't seen it close to tem00 at any point in time. The beam profile along with the mode hopping is bad at any temperature. The only reason I even bought this laser...
Just bought a spartan 300 and I'd really like a beam expander to go along with it. Please Pm me if you are thinking about selling one. Any information on where I could buy an alternative 10x or greater expander that can be screwed onto a spartan would be greatly appreciated.
I gave the why. I want to clip them to the tips of my fishing poles. I fish at night for catfish , and I need to be able to see when the fish are biting. I usually use glow sticks, but I want something that lasts longer. should be cheaper and easier in the long run.
I'm looking for some small LEDs that run on AAA, or AA batteries that I can tape/clip onto the tips of my fishing poles. They don't need to be bright just probably slightly brighter than christmas lights. Any suggestions or ideas?
