A scientist from the University of Stanford has a printable microscope the size of a bookmark designed which would cost just 35 cents to make. He has Foldscope especially devised for combating diseases in developing countries.
The Foldscope consists of several parts and printing paper kit can be put together in minutes according to Manu Prakash at Stanford University. To observe samples have to be stopped to the front in a groove, after which the user can scroll. Them behind the lens These are small spherical lenses converted 12 cents each, which are in a small hole in the middle of the Foldscope.
The user must keep the microlens so close to his eye that his or her eyebrow touches the paper. With both thumbs to move the sample. One led to the consumption of 6mW behind the lens provides relief. In combination with the small battery, the LED would last the 50 hours. The lens magnified 2000 times as the user keeps him close to his eyeball, which, for example pathogens are visible.
The microscope can be equipped with different spherical and aspheric microlenses, as described Prakash along with colleagues in his research paper . Also, by combination with a diffuser and dark field microscopy condenser as possible, while at the same fluorescence microscopy, the use of lens arrays and projection among the possibilities.
"I wanted to make the best possible disease-detecting instrument that we could distribute almost for nothing," says Prakash. "What came out of the project, is what we call a disposable microscope." Except for this purpose he uses the instrument to learn. Youth microscopy
