More info

The beam expander does exactly what the name implies - it expands the beam. Because of the limitations of using only one focusing mechanism on any focusable laser, if you want to add versatility and the ability to focus the beam at multiple distances, a beam expander will help you do that.

When you attach the beam expander to the laser unit, you can either diverge the beam or converge the beam at longer distances.

Using the focusing ring on the beam expander (the ring with ridges on it), you can control the focal length of the beam. Also note that the focusing ring on the laser unit itself also affects the focus of the beam expander - they work in conjunction with each other. The focusing ring on the beam expander can be rotated from one end to the other of a total of 13 full rotations so don’t be surprised if you can seemingly rotate the focusing ring on and on.

These expanders are cool but for some reason don't provide a perfect beam. They defract the beam. I own 3 lasers, and these expanders make the beam split in two, and send massive defraction rays out of the lens as well. Adjusting these is tricky, and I'd recommend adding a very light coating of grease to the threading.

They do make the laser much more fun, but by no means are these close to perfect. My 465nm laser goes a confirmed 5 miles with the expander attached.

LJ 'Hakzaw1' H 02/05/2020 5	I own lasers from many makers. Without a doubt JL and Mr. Gray have set the bar very high. Other laser makers would be wise to try and do as much for us as Gray has. They/he goes the 'extra mile' to make everyone a very happy customer.. thanks Gray and everybody else at JL.org . Know that we will keep you and your family in our thoughts and prayers especially in light of the Corona virus.

Alaskan from Laserpointerforums.com 12/09/2019 5	These are made for JL pointers, but for what they are, they are the highest quality beam expanders you can buy for the price they offer them for. I would say the can compete with beam expanders which cost several times their price too. Very happy with mine.
