Researchers have created the world’s smallest silicon LED and holographic microscope that opens up a wide range of potential applications, including turning your smartphone camera into a portable, ...

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 ...

Researchers have shown that consumer-grade 3D printers and low-cost materials can be used to produce multi-element optical ...

A microscope used by Antoni van Leeuwenhoek to conduct pioneering research contains a surprisingly ordinary lens, as new research by Rijksmuseum Boerhaave Leiden and TU Delft shows. It is a remarkable ...

Claimed to be the smallest ever, a bright sub-wavelength silicon LED has been fabricated for use in a high-resolution lens-less holographic microscope, according to researchers at SMART in Singapore, ...

Researchers in Australia have invented a new kind of optical lens that could be combined with a smartphone camera to create a microscope for diagnosing skin cancer or identifying agricultural pests.

[Amen] obtained a microscope whose light source was an incandescent bulb, but the light from it seemed awfully dim even at its brightest setting. Rather than hunt down a replacement, he decided to ...
