So, a little update here......











I have done a little work recently. I started on the back panel with my ILDA and dmx in/out's, power connection/switch, key switch, and some LED's.


Then I started on the table where I mounted the 4 gm-20's I have here(2 more on the way) and one of three cover interlocks.. I purchased a nice beam launcher from Micro Laser Labs that will split the beam 3 ways and send it out into the room for other effects. I'm still missing some screws to mount the gm-20's to the mounts so they aren't all setup yet.




I still have allot of work and this is only still the very beginning so check back because there will be allot more here soon enough

Very sweet idea! Can't wait to see how it progresses..

Me either.

I just made a $60 order for various bolts and bits, as soon as that arrives I can do some more work.

Check back soon!

I bet that no matter what you’re not going to get more then 2.7W after optics if that much. You are going to have a lot of loss, and I belie with test done on pl that it’s better to have reds that pass blue meaning you want to go green blue then red and you cut your losses a lot for both blue and red “I believe”, I forget where the post was but I thought it was interesting. Plus you’re going to want a really good filtration system as its going to suck to have to clean all of those optics...... also I don’t think it would be feasible to run 2 beam shows out of the same projector as since they will be so close together it will just look like 1 projector as it is just with more beams in it so you would be better off going with 1 really fast scanner then 2 in my opinion unless it was directed to that one guy in the center of the audience looking directly at the projector that can see they are spaced 2’ apart.

But despite how I don’t think this is going to work as I agree with Andy your going to be hard pressed to find thos optics it will be a good project and be interesting when it’s done.

So good luck and remember no matter what it will be a great learning experience and hopefully you will have fun and that is what matters.

Don't take any "real" info from that first drawing, I made that before I really started planning anything. Almost everything has changed but I wanted to leave it up to demonstrate my "idea"
Those SP20's are going to be 1)DT40 wide(tuned to 30) and 1)DT30..Both are GREAT scanners.
...also I know that there will be losses, of course it will be less :P
The dichros were difficult but I already have them sourced so its only a problem of $$$ now and that's only a matter of time.

Regarding running 2 beam shows at once, its only for simple beams and and the more complex the show gets the worse it will look, but its a great effect and something that nobody else has,It's also going to be the very last thing I add to the laser.

The case will have 4-6 filtered fans all sucking into the case and blowing out the VERY LARGE opening in the front of the case. This isn't for cooling but to try and keep as much dust away from the optics as possible

I have a Semrock 650/630 combiner, I can speak highly of it, but we needed 20+ people in the PhotonLexicon group buy to get the cost of a coating run down. I'm remembering 150$ and shipping for the group buy price, and 435$ for one...

Guys, when you look at the transmission curves, Edmund's dichros are often crap. everybody goes to Edmund just because they are a bit easier to order from. There is better stuff out there from places like One Stop Laser Shop etc..

Good to know, I just made a OSLS order yesterday and I feel another one coming up .....

Where did you get the tiny beamtable? Also, where do you get hosts/pre-assembled lasers you can fasten to the beamtable? On top of that, do most of these units have beams that leave at near-perfect angles, and that are at the same height? it seems like otherwise you couldn't get them to line up.

thanks,

The beams often don't line right up naturally, but that's what shims and adjustable optics mounts are for.

that's what I figured-but are most labbie lasers from companies ready to mount, and also where are these small tables from?

will

They are from One Stop Laser Shop...

A little update for today...
(youtube didn't like the video)

Hmm, cooler than I expected it to be. Thats only with one color too, can't wait to see more...

Expect to see a 250mw 473nm in the next 2 or 3 weeks when the tax check comes and the 532nm will come as soon as ebay item Axis 211 Security Network Camera + Outdoor Enclosure - eBay (item 250577220256 end time Mar-10-10 07:31:24 PST) sells

I have a >500mw RGV laser that's stuck in a USPS claim. When I get that back I will have the rest of the parts to pretty much complete this.

Guess what: I wanted a beam table, so I found a really cheap way to make one! My mom was throwing out one of those metal cookie sheets (no idea why) so I took it and drilled a hole where all these little divets were, and now I have a metal sheet with equally spaced holes! I just need to flatten it out a bit...

will

A beam table should be quite thick. At least around .5" or 10mm. I don't think a cookie sheet will be stable enough to work for you.

I have a 200mW 473 on the way too. It got stuck in the damn Chinese new year though. I'm as excited as you are, this will be my first exotic laser color. I have a white fusion but its not the same a the real blue.

It's a thick-ass metal sheet, at least 10mm I think. The only problem is a light bend which I have to hammer out.

wouldnt model rc car servos work better than solenoids for the mirrors

The GM20's that I have are the perfect thing to use. They are SUPER fast and almost completely silent. R/C servos are WAYYY to slow.

another little update.....I just ordered a new >250mw 473nm LW Module and new LW Dichros and the NEW DT40 WIDE scanners.




Expect to see them in the next few weeks

oh ok. also i'm still just in the learning stage of scanners. i wasn't sure from the diagram how the solenoids were used. but now i understand. thanks.
