I was tearing down an old digital camera, and I found this little plastic lens in the pentaprism housing. It looked about the right power for the camera on my digital phone, so I taped it in place and tried it out:
ilicone gel, a fine-tipped tool, a cover slip, and an oven are all that is needed to transform a regular smartphone camera into a microscope to produce high-resolution microscopic images, a researcher from the Australian National University (ANU) Research School of Engineering has discovered.
I went and looked them up. I'm going to see if I can duplicate that result. I'm a bit uncertain, since most lenses are basically sections of a sphere, and these gel lenses are parabolic. Aspheric lenses are notoriously hard to get right. I'm rebuilding a pantry right now, but when that's done, I'll see what I can do. Sounds fascinating. I'll need to get a nice secure frame to hold the phone for that kind of magnification. I've got an old steel frame for a projection microscope that might do the trick.
