New Flat Lenses Technology Could Offer Smaller Lenses with Zero Chromatic Aberration

A new technology dubbed “achromatic metasurface” from Harvard’s SEAS aims at making Chromatic Aberration (CA), a thing of the past. Moreover, they are planning to do it with a flat lens design.

A flat lens prototype was introduced back in 2012, but it could only work with one wavelength creating significant Chromatic Aberration

The lenses we know are curved, making the acting like a prism and breaking different wavelength in different angles, creating an effect called Chromatic Aberration. Most lens companies have technologies to overcome this problem by either including several glass elements in the glass or by using different types of glass (like ED glass for Nikon).

New Tech Enables Taking 60 FPS Movies (And Selfies) Inside Our Arteries

You’ve probably heard of Nanotechnology, and you probably know that its nothing new. But what if you heard that nanotechnology now puts a camera in your blood vessels?

I’m not talking about just inside your body. I’m talking about something so small that it can travel through arteries in your body and not end up causing an aneurysm. A scientist named F. Levent Degertekin has developed exactly that. The tiny camera is not only just a breakthrough by definition; it’s apparently a breakthrough in its performance as well. It was developed to project real-time, 3d, high definition imaging of the inside of our vessels, arteries, and hearts. The prototype developed by researchers generated images at 60 frames per second.
