Some good color shots, trying to clean my lens

Just a couple shots I got when I was trying to use my camera sort of like a microscope to see whats going on with the lens. And a couple I took of the unfocused beam plus one of the dot indoors. My camera captures the color perfectly, though it does get overpowered indoors and loses its ability to focus when inundated with the blueness. Probably some setting I should adjust. On that note, I'm pretty sure the spot on my lens is between the two elements right where they touch since cleaning from either side has done nothing but dirtied up the edges so far and probably taken off some of the AR coating with my vigorous scrubbing. Ill probably just order another. (no its not on the diode window, it rotates with the lens).

Indoors, flash on

outdoors, daylight

indoors, dim lighting

Good macro range on your camera.
You should bring your pixel width to 600 - 800 so it will fit the screen without side scrolling.
Your last shot needed a tripod.

I doubt you would see that spot in the focused beam.

This is a result of the lenses being too close to each other, possibly making contact.
I have a lens that does exactly that.
I added another spacer between the elements and the beam was much better with no ring in the center.

What kind of tool loosens that ring? from the scratches you can see I tried, to no avail.

pair of pointy tweezers did the job, then held the lens for cleaning. The top lens had a spot of something on it. looked like something left over from the coating process. Only downside is now all of the scrubbing has added some artifacts, ohwell. When focused it runs good.

A cotton Q-tip, probably why I scratched it up a bit but I didn't have anything else that could get down in there before I took it apart.

What's yours doing? like a flashlight? It dirty or clean wont affect the ability to focus, just the power output and cleanness of the dot. The issue with mine is only noticeable when its very defocused as in the top pic. If yours looks like that all the time maybe its in backwards or way out of focus?
