Re: Questions about the microscope needs of the community

Tim, I'd love to help you out with the dissecting microscope problem,
but i'm afraid that is more than a little out of my skill level
engineering wise. As far as everynody else is concerned, it sounds
like I need to collect more data about my optics, I've suffered a lack
of work time due to the holidays, but am strapping down for a catch up
session. I can assure you I'm getting quite decent resolution with my
current setup (nothing near gigapixel quality, but 720p video, and 2
megapixel still capture), but as magnification increases my setup will
suffer from field of view shrinkage, though depending on how my lens
stands up, that would increase resolution (it seems like I haven't hit
the lens resolvability barrier yet at least) Marc, do you have a list
of different lenses (where they came from), and their characteristics
by chance? I think I've read everything hackteria has written about
microscopes, but I can't find any list of where your alternative
lenses come from, it would be save me of redoing tests on whatever
webcams you guys have already worked with... As a side question, does
anybody on the mailinglist have access to a 3d printer and/or laser
cutter (can compensate for time to a point, and materials and shipping
would be covered by me of course), preferably in the US? Companies
like shapeways are great, but their printing fees are quite high for
prototyping work.
