The world's smallest LED developed by researchers in Singapore has paved the way for converting existing mobile phone cameras into high-resolution microscopes. A new type of LED, which is smaller than ...
This is the world’s smallest silicon (Si) light-emitting diode (LED) - smaller than the wavelength of light - with a light intensity comparable to much larger, state-of-the-art Si LEDs and with ...
A physics-based autofocus method uses dual LED lighting to detect and correct defocus in microscopes. It enhances imaging ...
