Step 1: Materials

Picture of Materials
You will need the following materials, most of them are fairly cheap and can be bought on-line or at any hardware store, I made this for any Nikon camera but the list is universal:

Camera Body Cap (Available at ebay for Nikon and Canon).

PVC pipe slightly smaller in diameter than the body cap (I used 5cm / 2" for nikon cameras).

Sheet of foam (Ethylene-vinyl acetate) 5mm / 1/10" thick.

Mate black spray paint.

Crazy glue or any other cyanoacrylate based glue.

A ruler, a drill, circular saws, scissors, hot wire and other cutting/measuring instruments.

Step 2: Cut PVC pipe and spray paint.

Cut the PVC pipe, I cut it to a length of 5cm / 2" but the length is up to you.

Keep in mind that the longer the PVC pipe the more magnification you get from the microscope. Pipes longer than 10cm / 4" will require exposure times grater than 4 seconds (under ISO 200).

After you've cut the pipe make sure the base and the top are straight by sanding the edges. Once you have a pipe that will stand straight on a flat surface you can start painting it.

Remember to use mate paint, otherwise the glossy finish will cause reflections that will show in your photos. While painting apply several thin layers of spray paint.

Step 3: Cut and glue foam.

Cut (using hot wire) the foam to make a ring (like the one on the photo). The outside of the ring should be of the same diameter as the PVC pipe, the inside of the ring should be slightly (about 0.5cm / 1/5") smaller than the eye piece of the microscope that you will use (so you need to measure the eye pieces before you start).

Once you've got your ring, apply a small amount of crazy glue to one edge of the PVC pipe and glue it to the foam while applying pressure.

I really hope that the above pictures aren't your spermatozoa.

Great idea! another use for this device would be for the exact opposite approach... a telescope. One could even turn a decent telescope into a really strong telephoto lens.
Smart !  hehe Love how you said heres a few samples made
Sperm, lol

Nice work! One word of advice about crazyglue and optics: Never work near lenses!!! The fumes of the glue react with traces of grease on the lens, forming stains. The police makes use of grazyglue to make fingerprints visible this way.

Thanks for the feedback and thanks for the advice on crazy glue, I'm sure it will be useful to others.
