Laser projector

Post by MaxCFM »

I've been lurking around this forum for a while, trying to learn as much as I can on various subjects. I bought one of the 3D3 Solutions SLS scanners nearly a decade ago (for the small business that I had at the time). The scanner has been collecting dust for many years but I've recently begun upgrading it for casual/occasional use on projects. I have 2 Point Grey rolling shutter cameras (FL3-U3-32S2M-CS) and an Optoma HD66 DLP projector. I generally scan small objects, usually small engine parts. I see many others forum users are using SLS for engines ;)

The projector is getting old and less reliable and I am looking for a reasonably priced replacement. I've read the posts in the forum about many different projectors but I haven't seen anyone ask about the Epson EpiqVision Mini EF11 laser projector. It's less than $700 and it has a throw ratio of 1:1. Laser projectors don't need to be adjusted for focus, right? It seems like the calibration would be limited to the focus range of the cameras only - instead of the cameras and the projector.

Perhaps there's something that I don't know that disqualifies this projector from consideration but I thought I'd ask about it. Thanks,

Brian

I can't speak to that laser projector, but I have tried 2 so far (A Casio and an early Epson). For reasons I never took the time to figure out, surface distortion was Horrible. The scans were completely unusable. This was maybe 4 years ago, and now there are some very interesting laser base projectors I'd like to try. One thing to note is that the laser is merely the light source. At least in my experience, the projectors still uses the mirror array (and thus has window screening effects you need to evaluate [see square vs diamond pixels]).

If you have a place that has a good return policy, (newegg, B&H) Try one out and return it if it doesn't work well.

That's great information from your experience with other laser projectors. It may be true with the Epson as well. I was thinking along those lines of buying and returning but wasn't sure what retailer would be best. I've bought a ton of computer hardware from Newegg but, thankfully, I haven't had to return anything yet. I don't want to get stuck with a projector that isn't right for what I need. Thanks for the advice.
