The microscope was a big hit at the health workshop. I still feel somewhat guilty that the people of the community thought they were actually looking at microbes swabbed from their hands, rather than critters taken from the local cow pond.
I really like microscopes. I get really protective of the one I use at school, and I've been known to grumble when I find the first years have left oil on the objective lenses again.
When I get a good microscope, I try to hang on to it at all costs. You never know how good you have it until you look at a scope that only focuses on a single point in the field, or has a light that is never quite bright enough.

One of the various gadgets I got for Christmas this year was this unique camera. Basically, it's a microscope that's powered by the computer's USB port. It features 4 white LEDs near the lens for illuminating the material which you are trying to view.
The camera has the standard Zoom and Focus rings similar to those on a standard microscope and/or D-SLR lens. The button visible on the top is the shutter button, allowing the user to take a snapshot of the object they are viewing.
I will post some images taken with this camera.
I bought a $75 microscope yesterday to look at our local algae with.
This is digital scope with a usb cable that works well with my mac. I
did buy a piece of $15 software called miXscope to take pictures,
make movies, make measurements, add subtitles, and draw on the
screen. The scope does not take very good 60x and 200x photos out of
the box due to a low power LED backlight. After fifteen minutes of
getting frustrated I took the toy apart and added a 1 watt white LED
and now I've been getting some great results.
The only thing that does not work in this microscope, is the optics... Although LEGO has produced a magnifying glass brick, I never even took an attempt at getting something between a 20- and 600-fold magnification from them...
This is a run-of-the-mill inverted microscope; an instrument you will find on any laboratory where tissue cultures are handled. It is inverted because with a normal microscope one looks down on the specimen. An inverted microscope allows the user to look from below the sample. With the thick dishes, flasks and plates used for tissue culture, and with a volume of nutrients on top of it, a lense can come a lot closer to the specimen from below! Getting closer, means higher magnifications are possible.

Les Actinopodes sont des organismes unicellulaires qui forment un embranchement d’organismes aquatiques à symétrie généralement sphérique. Une bonne part d’entre eux possède des squelettes externes calcaires ou siliceux, hérissés de fins pseudopodes (filopodes et axopodes) rayonnants. Leur diamètre est de 40 à 200 microns. Ce sont de prédateurs capables de capturer le plancton grâce à des substances adhésives présentes sur leurs axopodes.

Some time ago I bought this cheap noname Microscope objective at a flea market I think I paid 20 SEK (about 3 USD) for it.
It's a finite 10X Microscope objective with a intended tube lenght of 160mm and na 0,25.
The threads are RMS.

I have recently obtained an WWII-era research grade microscope, the Leitz Ortholux I. It was sitting in a friend's closet for a long time and the optics need a lot of alignment, centering, and some dusting love. Also, the power supply hasn't arrived, so this shot was obliquely illuminated using a dim flashlight.
This is the edge of the slide clamp spring arm seen at approximately 125x magnification. The parallel grooves are polish marks. The objective is a Leitz 10x achromat and the ocular is a Leitz Periplan GF 10x (there's a 1.25x lens in the nosepiece as well).
I just wanted to see if I could hang my camera above the trinocular camera port and get an image. The image looking down into the camera port visually is much sharper than this, so there are some serious image plane alignment issues that need to be worked out . More to come.
I made this from the instructable here. www.instructables.com/id/10-Smartphone-to-digital-microsc...
