How do I fix Zeusray zoom focus

Searched but can’t find it, How do I fix my Zeusray…
When zoomed out the beam doesn’t get as tight as it should.
What do I need to do make get it better?

Thanks

Have you looked at the combined thread? There have been a few different variations.

If you take the lens out and move it slightly farther away from the LED, can you get a focused image of the emitter that way?

I think you need to clarify what’s wrong first. Only when people know the issue will they be able to provide or offer solutions.
