Focal length of an ortur 15 watt module.
Meant to say “what is the focal length of the 15 watt Ortur?
55mm from the heatsink.
It should be adjustable by twisting the lens.
My 15W Diode is fixed focus and a 20mm metal cylinder was included for calibrating or setting the focus. I don’t think I can twist the lens.
Ah, ok - I haven’t seen the 15W units.
I recently received a 15 watt mod from Ortur AliExpress store. It has n adjustable lens. So, I’m set up at 55 mm from bottom of mod to the smallest laser dot I can see. Works great.
55 mm ! My focus cylinder supplied is 20 mm.
Interesting.
Well, as you go through all these posts the focal is all over the place. I read today 35 mm and you say 20 mm. It seems that 55 works for me, but I haven’t played with the new 15 watt that much. I know the 7 watt was 5 mm for me.
I meant 55 mm not 5😉
