Here is an economical way to experiment with light, color, and optics. You get one Red LED light source, one Green LED light source, and one Blue LED light source. The three LEDs can be controlled ...

Engineers have developed a technology that turns a conventional light microscope into what's called a super-resolution microscope. It improves the microscope's resolution (from 200 nm to 40 nm) so ...

Overcoming the resolution limit in a light microscope of around half a wavelength of light (about 250 nanometers) is one of the most significant developments in optics. Due to the wave nature of light ...

Receive emails about upcoming NOVA programs and related content, as well as featured reporting about current events through a science lens. The new microscope uses a 405 nm laser—the same wavelength ...

Microscopes magnify light. It makes sense that having more light reflecting off of the subject will result in a better magnified image. And so we come to Aziz! Light! It’s [Steve’s] LED light ring for ...

Modern imaging is contributing significantly to giving us a better understanding of how our brains work. In the long term, this will also help us to treat learning disorders in a more targeted way and ...
