need big mirror scanners, speed is least of concerns

[norty303]

Get the PT-A40 with the larger mirror option.
You'll overspill the mirrors a little, but not significantly so. It's what I used in the 20W projectors I built and I think we had nearly 7mm beam in some dimensions.
Or the PT-20's with the large mirrors. I think there's also a DT-20 specifically designed for slower speeds but larger beams.

I see. Thanks for the information.

Pangolin Compact 506 with 8mm aperture, with Laser Fantasy Amps… Will cost a little more than the coin in your pocket, but will have a nice setup when done.

Would much prefer if others would chime in with info about the chinese scanners. Nothing against Pangolin, but to me its like Apple of the laser world, quality but quality comes at a price. I haven't had issue with chinese scanners so far (the small mirror ones) and they are much more affordable.

That said, I like how 506 website has info on what size mirrors are available and what each are capable of. What I don't like is 1) no amps so separate purchase and tuning and 2) asking for credit card info before telling me how much it costs. I know Pangolin isn't a scam website, obviously, but I wouldn't want to give that info without even knowing if I want to be their customer. Asking a refund after I'm charged more than I assumed I would is one unpleasant scenario. PM me please if you know how much they cost and for whatever reason that info shouldn't be public.

But again, if anyone has info on PT or DT scanners, or other chinese scanners for that matter please share your experience.

Lol, you posted right before I was making a reply to the rest.
Thanks, now I know they are practical.

If/when you get the time could you give more info or suggest who I could contact for more information. I'd contact Phenixtechnology or Dragontiger directly but my experience with chinese customer service so far has been they tend to give inaccurate technical details about their products.

The info I'm asking is what scanspeeds I can expect with these scanners and these mirror sizes. For example I'm confused why there's PT-A40 and PT-A20, it doesn't look like all the difference is just the mirrors, they have noticeably different motors.

[norty303]

I doubt you'll get much response from them.

I will say that if your needs are just <10kpps then any of those sets mentioned will do it. I run the PT's at 30k+ sometimes. If its just beams as you say, then they'll all do just fine, and probably run ok at 20k no problem.

Thank you. I forgot to ask one important question, what scan angle did you have in mind when you were saying PT-A40 will overspill a little?

And a question to everyone with big scan mirrors, is there anything extra to be careful when operating these scanners? Maybe the mirrors have a risk of shattering when moving too fast or something of that sorts? If yes, what tips to avoid that and tell when speed is too high for the mirrors.

[norty303]

0 degrees, they overspill at rest, and obviously more as angle increases. The PT DT 20's sound like the sort of thing you're after though, and should come with a paddle big enough to accommodate your beam.
As for speed, you'll see the images starting to distort as it gets wider and/or faster. This is one of those things you'll get a feel for. The noise can be a give away too, and something you'll tune into after a few hours with the thing open on the bench. Some are noisier than others, the 506's were significantly quieter than anything else I have, even when pushing them too significant distortion.

The C506 with 8mm aperture might be a good fit for you. Plenty of room especially if speed isnt hugely important.

Working on a 6mm aperture mirror set for C506 right now but might be a bit small

I have these basically in stock right now.

These were originally custom designed for Rick Hale (slicklasers). I believe he uses them in some of his very high power projectors and can tell you exactly what you can expect in terms of performance.

We typically sell just the scanners for $350, and then Alex Hay at Laser Fantasy provides and tunes amps and supplies cables.

Feel free to send me an email at the address below and we can get into a private discussion about what you need and budgetary restraints, and we will see what we can do for you!

I will.

Yeah, after I checked their website for the mirror sizes and tested in my 3d editor,7mm is way too big for this scanner, unless I have the rest angle wrong (not 45)

But you said there is a larger mirror option?

If they'll give me at least the CADs of the mirrors (positioned) I'll be able to test what beams can fit, and share the info here. I don't want to risk the money and rely on the data on their website.

Good luck getting the Chinese to provide any kind of CAD, especially with mirrors positioned. The best reply I would imagine would be received would be "Kindly find attach drawing of scanner mirror"

Below is a screenshot if your 6.5mm beam with reference to our 8mm aperture mirror set. With that size beam, these mirrors can scan about 50 degrees in the X direction and 60 degrees in the Y direction before any kind of clipping/overspilling/etc. Of course you can push further if you want to and lose some of the beam...



By the way, we make all this CAD available to anyone, customer or not. It can be downloaded directly from the C506 page of the ScannerMAX site.

Let's keep this thread neutral. I understand different people have different views but I don't feel it's best for a Pangolin employee to criticize Phenixtech or DT, true or not. A 2d diagram with top and side view + knowing the rest angles of the mirrors should be good enough and I'll post here again after I get that info from them.

I'll email you for Pangolin specific questions.

Thanks.
