Focus ring fell off

I turned my focus ring too far out and it dropped onto the floor. Does the focus ring have a lens stuck to it? I looked everywhere on the floor and couldnt find the lens. My laser does not focus anymore no matter how I turn the focus ring.

Anyone know where I can find a replacement part?

There is a lens barrel attach to the focus ring. If you can't find it back you can ordered it here,

Its probably loose. The lens is screwed into the focus ring ie the black cylinder in the aluminium ring (first pic) and the whole assembly is screwed in to the module on the host (second pic). If the lens is not tight in the focus ring, you'll keep turning the outer ring ie screwing it on and off and the lens wont move. Just tighten it up!:beer:
