Where else can I buy good modiules besides DTR ?
Last edited:
lolI bought a few random modules from DTRs laser shop and I am generally unhappy with the beam “quality”. Every one has artifacts and I want something clean. Where can I buy clean modiules ?
Thanks
3 element lenses are best for keeping a tight beam, Most likely you are using acrylic lenses, with those big circular artifacts are common.Ok, so I guess I should rephrase and say what are some good diodes ?
(*The artifacts are not dirty lens)
Is one type of lens better for a clean beam ?
Hi, I wouldn't use the word dumb you have the smarts really. It just takes a little time to figure things out when your new to something .Ok, so I guess I should rephrase and say what are some good diodes ?
I say module because I’m too dumb and lazy to build my own.

Hi, The 488nm diode can use an acrylic lens if powered low and that will cut the box reflexion.Ok, thanks. I have some G8s on my modules now, I’ll try 3 element.
funny you say that about the Sharp 488 55mw because mine with the G8 is pretty bad. Like my 7845 or whatever. It’s my new favorite color but it’s very bad unless focused to a fine point.
The bdr209 w/G2 isn’t too bad.
Lol, lower your damn expectations! don't expect TEM00 circular profiles out of anything but bluray and DVD diodes and Fabry parrot diodes,Ok, thanks. I have some G8s on my modules now, I’ll try 3 element.

Yea those are typical.. Try the DTR-3E-B lens, Would eliminate those as much as possible.I like the different shape spots, I just don’t like the weird stuff that shows up around it.
You can see here on my dirty subfloor what I am talking about...this is the super hot Sharp 488.
This (some type of exotic bird head?) is extremely annoying, it makes no pattern or sense...

The second one i can almost deal with because it’s almost symmetrical...it almost looks like it belongs there.
anyways, thanks for the replies and infos. I like to play with the focus and make big and small and round and square shapes, I just wanted to do it without weird artifacts. If I show this to my friends the first thing they will say is “what is that stuff” and I’ll be so embarrassed. jk
I guess I will just keep buying the stuff until I get some special/very nice ones. (Got that stimulus check)
