Passive, lossy materials with positive index at real frequencies can be used to realize optical antimatter under complex frequency excitation. Our approach enables arbitrary complex \(\epsilon ,\,\mu\ ...

Highest flexibility and performance for semiconductor, photonics and SR-Microscopy applications. (Nanowerk News) PI (Physik Instrumente), a global leader in nanopositioning and precision motion and ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

Researchers at the ArQuS Laboratory of the University of Trieste (Italy) and the National Institute of Optics of the Italian National Research Council (CNR-INO) have achieved the first imaging of ...

Our lens reviews offer detailed information on sharpness, distortion, bokeh, and all the other important factors that go into making a lens great. Our reviews give you all the information you need to ...
