New EYEMAGIC Scanners EMS7000

[Solarfire]

Is everybody not overreacting?

Someone states there hardware is great, others claim the hardware can't meet those specs.
In my opinion every hardware/software, designer/developer is obligated to its customers to give the correct specs and performances.

If an company can prove proof, made with the market accepted standard tests, that there products meet those standards, there is no issue.
If an company can't provide that info.. There is something wrong.

In this case, it would be best that Eye magic, provide everyone with the specs and show how they test and confirm these.
When proven, great.. Job good done! If this can't be provided.. uhm...

Would we not ask the same of Pangolin as soon as they deliver an new product, to proof that it can do what they claim it can do?

Besides who is right and wrong, there is always another issue that determines the choice of the product that your going to use, and thats money.
If something is to expensive for your budget, you can look at other candidates.
The satisfaction factor is always in the eye of the beholder.
Price versus performance.

If you take a look at post 309 then you will see that it has already been proven...
Funny thing how hard evidence is ignored and hearsay is taken as gospel. The Pango fraction still hasn’t delivered even one plausible shred of evidence, no pictures, nothing. Doesn’t that ring a bell somehow? I challenge anyone to come by to evaluate the posted results personally, until then I think it’s time to start looking in the other direction, meaning Pangolin!

Well, all 3 images does not show a good ilda frame.

Uh.. Yeah, right. Well then show me your 60kpps scan @ 10°

[cyberb0b]

Well you have an point there, but should the ilda frame not be perfect, if tuned correctly?

Also, i was surfing pangolin.com and there is a lot of scanner info on there.
It may be an bit dated, i don't know when it was published, but i suppose it gives some idea about the testing methods.

But still, Eye-Magic is the one that needs to provide us with this test results.. As it is there product.

Solar whilst I can't criticise your enthusiasm, the ILDA test pattern should look like this:



The inner circle is the specific test for scanner speed.

The other parts of the test pattern test for other aspects such as blanking, damping, offset, gain etc.

The inner circle should be perfectly round, have no tails and sit perfectly inside the square box with each compass point on the circle just touching the inside of the box.

Purely for reference Cambridge 6215H's claim 60K at 7.5 degrees: http://www.camtech.com/news/6215pressrelease.htm

White light, can you please list all the reasons there are for the circle not to touch the square, or appear otherwise scewed or not circular?

I know I'm not Whitelight, but at least allow me to attempt to answer your question. If the circle isn't touching the square then the scanners are being sent a signal faster than they are either tuned for or capable of. If it's not circular, then one scanner is tuned faster than the other scanner. If it appears scewed, then you may be scanning at an angle greater than what the scanners are capable of at the set speed. This is part of the reason I was hoping to see an unblanked image of the test pattern. With it unblanked, you can more easily see if the circle has been torn apart possibly indicating too great a scan angle for the set speed.

If you take a look at post 309 then you will see that it has already been proven...

Solarfire, I have to respectfully disagree. In my opinion the images in post 309 do not show a properly drawn ILDA test pattern.

Yes, I’m aware of how the ILDA frame should look ideally. So if you look at this scan in this link (page bottom) of the ILDA frame scanned by a set of CT6215s then they are obviously also not meeting up to spec since the circle is not touching the square left and right and that @ 58kpps 8°. Now keep in mind that the CT6215s cost almost double the price of a set of EMS7000, not to mention having to dissipate 300W of heat as compared to 100W with the EMS7000.

And these pictures of Buffos review of the ScanPro50 also don’t meet up then.

So take your pick of scanners and show me the ILDA frame @ 60kpps 10° then we’ll discuss the results again.

Regarding the swisslas pic, I would agree, it's clear that the X axis scanner is not running fast enough to keep up, however the Y axis scanner is. Regarding the picture that you linked to from buffo's review, actually, that is doing 50K at 6.5 degrees just fine, the circle is being drawn correctly. There are other concerns in the image though, such as the ringing on the middle horizontal line on the left side. I see this as a problem. While I don't fully understand why this is happening, I've seen this problem on quite a few scanners from China. This can also be seen on the 4 short horizontal lines below the square.

I think the ringing are mirror resonances which happem with too thin mirrors. Especially chinese scanners often use very thin mirrors as a cheap way to reduce inertia and increase scan speed. But if the mirrors are too thin they can bend resonantly and lead to such oscillations.
