650nm red light laser module industrial laser module adjustable focal length6.2mm(point-2packs)

Rescued my laser cutter

I used the pair to make a focus and locating indicator for a laser cutter. They have good focus range and spot shape and sturdy well protected wire pigtails.

Unusable and had to return. I hope their not all like this. I really need one that works and that doesn't move all over the place when it's rotated.

Showed up on time works great.

I bought this to make a target for calibration of automotive adas systems. It worked but not happy with the precision at a distance. The beam becomes to large
