New EYEMAGIC Scanners EMS7000

[dsli_jon]

And the person who made the suggestion buys me a new set of CT6215's (or EMS7000's) when they get...

Haha... I said "CT"s, Jem, not 'DT's...

G'nite..

Indeed... and, that's one 'area' that, imo, the CTs (6215s) seem to produce nicer-looking ('smoother') results.. at least vs the EMS 4Ks...

I'd prpopose testing each, side / side, with several-different of the 'standard' test patterns - one good one is known as the 'Aura Tech' one - with the large-circle, inside a box, with an 'x' from corner-to-corner, thru the center, with 'X' and 'Y' drawn-out, designating each-axis.. The other one that's a 'goodie', is the 'interlaced Grid', with the 'RYGB' / circle, in the center...

..try those two, at 'spec'd' scan-speed / angles.... then try the same side / side.. at 150%-scale.. ..then, slowly-past 150%... and see which still has the 'guts' to continue / at-what %, w/o going into 'freak-out' / collapse-mode... The EMS 4Ks just never 'collapse' / shut-down, into a 'static-beam' like the CTs, when being driven too-hard / large...

Very-keen to see how the 7Ks do in that regard, specifically...

cheers, Guys..

Hey guys,

When planters and I asked Tom if they did larger mirrors than the 3.8 and 5mm aperture mirrors he said this;

"The new model EMS 7000*is designed for the 5,3 and 6,8mm mirrors. This design, although faster, cannot be ''overloaded'' as the EMS 4000 can."

I'm not sure if he meant overloaded as in larger mirrors or being pushed to the extreme of scan angle.

It will be interesting to see.

I believe he was rather speaking of overloaded "with oversized mirrors", a reason can be that unlike the 4000, the 7000 uses a monobloc mount and so limits the space between mirrors... Don't know why but it could be due to the big amount of heat generated by the galvos when drived at 60k (EMS4000 mounts doesn't really act as a heat pipe).

That's what Tom said me : a 60K scanner scanning the ILDA test at 60K @8 deg needs 8 times more power than a 30K scanner scanning the ILDA test at 30K @8 deg. Furthermore the 6.8mm mirror has twice the inertia of the 5mm mirror... So a lot of heat generated !

As far as overloading the 7000 with excessive size/speed, mine supported my tests pretty well

I bit the bullet and ordered mine too. Got the two supplies and, the Soft Start as well. Now... to find someone knowledgeable about electronics.......

Not bad. 1 month and 4 days. First dumb question... I ordered 2 supplies, figuring I ordered 2 sets of the Eye Magics but... I still don't know anything more about electronics than I did a month ago. Does one use 1 supply for a set of scanners or, do you use two supplies (one for each amp)? I did a trade deal for one of the sets of Eye Magics so, if I only need one supply, then I can list the other in the general Buy/Sell thread unless somone that bought the EMS 7000's is still searching for a supply and doesn't want a 5 week wait. We'll deal with the whole issue of that fact I have no clue what I'm looking at in this box later! I may need some hand holding on how to hook these up!

Brad,

Unless you have a +/- supply (unlikely), you will need a pair of supplies tied together to provide positive and negative 24VDC to the EMS-7000 amps. Each amp will be powered from this pair of power supplies.

[Bradfo69]

That would explain OSLS's offer of $125 for a power supply to accompany the Eye Magics when we bought them. In retrospect, might have been an easier solution.

What power supplies did you get? The ones meant for audio amplifiers?

If you got the +/-24V version you only need one supply per scanner set.

It's been a couple of months since the group buy and I'm wondering if there has been a review of the performance of these scanners.

Yes, I got the ones mentioned earlier in this thread: http://connexelectronic.com/product_...roducts_id/123

Greg said I need two. You're indicating I'm going to be o.k. with one. 'Tis a puzzlement!
