This is the next generation of the low cost teaching microscope designed to be built and used by students to learn microscopy. Depending on your choice of lenses, this can cost between $0.40 and $3.50 per microscope.
- 3D printed holder for lenses - This makes it easier for students to install them and keep their fingers off of them. I borrowed this idea from the good folks at Legoscope (http://designscience.ucsf.edu/lego/home.html)
- Snap-together design - No glue. This version slides together into place.
- Fewer pieces - We've reduced the number of pieces and it doesn't require a dowel anymore.
- This version can still use disposable camera lenses but I purchased some higher quality lenses in bulk when I implemented for classroom use. (See instructions for more details)
Once again, Angi has made a great video for us at http://vimeo.com/73818990
Please Note: This version is slightly different from hers. I've removed the extra slide stand and integrated it into the comb. I've also removed the lock-ring (everyone had trouble with it) and replaced it with a clip that snaps snuggly over the end of the focus axle. I have included an illustration of how it snaps on.
If you want to get the Chinese lenses we used, we got them from GS Optics (www.gsoptics.com) and ordered lens 2826, ~15mm focal length, 12.7mm diameter.
The resulting image was about 100X magnification.
An alternative is to use lenses from disposable cameras.
After playing with various options, I opted for a 3mm opening for the objective. You can hold the lens in place with a little dab of super glue. Try to keep it on the edge so that it does not affect image quality.
