Noticed the 445nm is also 4.2mm so will be a higher percentage loss of that also, leaving only the 532 to shine through.
Starting to look more like the dt40's are a better option.![]()

I've got a set of wides sitting around on the shelf as a result of the 3mm aperture mirrors, just not typically big enough for modern diode lasers. Great scanners but useless mirror size unless maybe a dpss or opsl only build, or don't mind trading a little divergence for a smaller beam size and extra costs of telescoping. I second the DT40pro's. They're nicely built. Even DT30's are a real bargain as the performance difference is not always readily apparent unless pushing them hard in graphic shows. Both available with the larger 5mm aperture mirrors as an option.
Thanks for the offer steviobee, but I've decided to go with the dt40 pro's as well and will be putting in my order this coming fri as I need the unit for a job beginning of july.
Be good to know there wil be another unit not far from me though if ever the occasion should arise and you ever fancy pairing them up.![]()
For whatever it's worth, I'm still debating between the pros and the wides.
I hate losing a little 637 (don't mind losing a little 445), but I think the loss will be minor.
The wides have 5mm wide mirrors designed for a 3mm beam... the 637 appears to be about 3.5mm. Of course, the greater the scan angle, the more lose it will be but my gut feeling is that it will be pretty small.
I'm still trying to find more opinions about this though before I decide.
I'm not sure how often I will want to scan "stupid wide", but this PJ is for experimenting with various effects, and scanning "stupid wide" is something that was exciting for me.
I'll post again if I find anything more out about how much loss I should expect.
If anyone with more experience can chime in, every opinion is appreciated.
And whether I get pros or wides, I will ask that they be tuned for 30kpps.
Thanks everyone for the help so far,

i have dt40w's in my projector and i can fit about 95% of my beams onto the galvo mirrors.
the lasers in my projector are:
1W+ DHOM 532
2 prism corrected 445's combined with a pbs cube
4 642 diodes knife edged (kvant).
the only spill i have is from the 445's and it's not much.
suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.
1) 30kpps
2) no. i don't do beam shows.
i would have been just fine with the dt40pros.
there are some videos of my work here (this is all done with my dt40w's): https://www.youtube.com/user/swamidog

Just to update everyone-
I have ordered the N-RGB3W from GSL with the DT40Wides.
All the info I could gather suggested the loss from the smaller mirrors would not be significant, and the ability to scan silly wide just makes me smile - even if I won't do it very often.
Thanks to swamidog, gottaluvlasers, and everyone else who has contributed their knowledge to these forums and helped me figure out what I was looking for.
And thanks to steviobee for informing me about the new case design - it appears to be an option only for those that ask for it, and I would not have known about it if not for steviobee's post.
This new case is exactly what I wanted - no silly sound activated pattern junk, just a nice clean case with ILDA input and a centered aperture.
I will post pics when I get it.
