Experts from Stanford University created a microscope from a cardboard which can increase the image in 2000 of times. But its main feature is the price which will be less than one dollar.
The new invention is called as FoldScope and gathers from a piece of a cardboard, a battery, the diode and the lens built in paper, thus the weight of the device reaches only ten grams. Process of assembly of the device does not demand serious knowledge, and to carry out it it is possible in only some minutes.
It is noted also that researches showed accuracy of adjustment of components in hundred microns. It managed to achieve thanks to self-adjustment of components at a cardboard tension.
Samples of images on a cardboard microscope
For use of the device it is necessary to include a light-emitting diode and to approach an eye to an opening in a cardboard. To adjust sharpness, it is necessary to move a paper begunok, and by means of another a begunka it is possible to move a sample under review.
According to messages of developers, such microscope will be very useful to doctors and researchers in developing countries where there is no possibility to use main and the road a microscope. School students and students can use also new invention, after all such microscope will be compact and has a minimum of fighting details. The charge of the battery will suffice at 50 o’clock continuous operation of the device.
The description of a cardboard microscope of FoldScope, and also the instruction on its manufacturing are published in online library arxiv.org.
