Hey fellas,
so it turns out i have a few LPC-840's to experiment with, i thought i was going to be working with the 836's but nonetheless, i bought a 660nm heat sink module + host from ebay for it, i think it came with a m9x0.5mm plastic lens.
Iv attached a picture below, my question is should the beam be diverging this much?
Iv also tested the power output of these bad boys and they are horrible, i could hardly get over 300mW out of these and they are supposed to be rated at like 500mW.
Also i have tried focusing the lens by screwing it in and out but it stays pretty much the same.
