Researchers develop an economical microscope that uses holograms instead of lenses

With the advancement in technology, things have become more compact and economical than they were earlier. These high-tech innovations are readily needed in medical and other related fields to generate reliable, portable and low priced equipments. One such similar attempt comes from the researchers from the University of California, Los Angeles, who have created a compact and highly economical microscope that uses holograms, instead of lenses.

Microscope

The archetype of this microscope is ready. It’s a small sized device that runs on AA batteries, fits in the palm of your hand and weighs extremely less. The newly developed microscope costs between $50 to $100 per piece, and the data collected by this microscope is processed and converted into useful information with the help of a laptop or a smartphone attached to it. It is powered using AA batteries.

Lenses are the most expensive parts of any microscope therefore this microscope is the most economical of its type, because it works without these. Its working is quite simple. The microscope splits laser light source into two beams. One of which is headed for the sample whose image is to be viewed (some rays pass through while other strikes the cells and deflects off). The other beam is not redirected anywhere, and its interference with the first beam forms an image pattern on the smartphone sensor chip.

Another significant feature of this microscope is its two mode operation. One is transmission mode which is used to reflect liquid volumes, and other is reflection mode which is used to reflect solid materials. Efficient features and cheap price of this microscope not only make it world famous, but will also revolutionize medical practices.
