Our experience with grad students looking at assemblies for tin whiskers - 50X was not enough magnification.? 200X marginal.? They went back to SEM for hunting whiskers.?Any other digital scope stories in whisker searches?

You may want to consider acquiring software to generate PDF files. I've
sent photographs in JPG format to suppliers and customers
electronically, only to have them bounce back because of the size of the
Adobe Acrobat would be my first choice, but I know there are other PDF
printers on the market.

Subject: [TN] Trinocular Scope With Display
I may have an opportunity to put together a decent inspection station
for our lab. The choices out there have my head spinning, maybe some of
you have experience or recommendations to share. Not sure what we'll
have to spend, but this system will be used partly for customer
presentations, so I'm hoping we can do it up right.
This would be used for everything from FA on components, to solder
inspection on boards, to looking inside small chassis. Need capability
for image capture, and maybe a nice big screen so others in the room
Optics - Trinocular, zoom, good depth of field/working distance,
magnification from about 5-7x up to about 40-50x. Some have a lever
that disables one of the binocular eyepieces whenever you want the
camera to work, and I think this is a pain. In the archives I saw a
recommendation for a Meiji EMZ-8TR - any others? What about a 0.5x
objective lens to increase working distance?
Stand - Articulating, single or double boom arm? Counterweight?
Swivel? Biggest pain I've had is adjusting the Z height easily.
Usually you have to release the slip ring, lower it, retighten, then
release the head, and drop it down on the slip ring, sometimes heavily.
Is there any easier way to adjust?
Screen - maybe around 40". LCD, so no burn-in.
Camera - CCD or CMOS? Resolution? Output? What about Sony? Some
might think w
e'd be better off with a good hi-res digital still camera.
C-mount? Either way, is it realistic to expect that the image would be
close to what we see through the eyepieces?
Lighting - Probably a ring light and moveable fiber optic arms.
Anything new being done with LED's? Polarization? Any hints for
picking up tin whiskers?
Image Capture - Any special kind of card in the PC? Software? Probably
output in bitmap, convert to JPG. Don't need PhotoShop, but some basic
image processing will be helpful.
