3-D Lenses

Until a few years back we were satisfied with 2-Dimensional movies and pictures. One angle gave people all they wanted to know about a subject. They could imagine the extra dimensions. Then 3D technology came into play, and flat pictures weren't enough. But in order to capture an image in three dimensions, people needed to take at least two different images of it at the same time. To see the world in three dimensions, the human brain takes the slight variations seen by the left eye and the right eye and constructs one picture. In order to render things in three dimensions, movies have to re-construct that variation. But now the story is different it is not the film that is reconstructed the capturing itself is done 3-Dimensionally

After a lot of speculation and trials, the world has finally got its first 3D microscopic lens which has been created by Lei Li and Allen Yi of Ohio State University. This device is one of its kinds which are mainly because it gives the ability to see microscopic objects while they are stationary. Other such microscopes capture images of the subject by circling around it.

This device was crafted by the engineers on a precision cutting machine using a diamond blade because they believe that it can be made by using the traditional methods. The acrylic glass was cut by 10 nanometre spacing to result into a flat plane.

The top of the lens is surrounded by 8 facets like a gem stone which is not symmetric. This allows the user to see 9 different angles and hence giving a 3D view of the subject or object. This method has paved way for scientists to get better angles of microscopic objects.

The lens is compact, can be kept in one place, but can give scientists nine different angles on the same object at the same time. The microscope that uses this lens can't be entirely stripped down - the different angles still require a computer to merge them into one three dimensional image. The image up above is the lens' un-merged view of the tip of a ballpoint pen. Still, the overall version would be a great deal more compact and easy-to-use than current models.

The lens was designed to speed up miniaturization of technological components, and make it cheaper to shrink them down. It will also help speed up assembly. So the next iPad will be half the thickness, weight, and price. .All these factors will make the upcoming gadgets cheaper.
