From time to time, GearScout will post messages from the tactical industry that we think will be of interest to our readers. Meprolight, a world leader in a variety of optic solutions from ...

(Nanowerk Spotlight) Optical spectrometers are devices that measure the variation in the absorption and emission of light over a range ( the change in the absorption and emission of light with ...

A metallic quantum dot sandwiched between two superconductors – which functions as an electronic turnstile, only permitting one electron through at a time – has been developed by researchers in France ...

Plasmonics can be used to enhance the emission properties of single quantum nano-objects and use them as bright ultrafast single-photon sources. However, plasmonic trapping single quantum objects have ...

Over the last several years I’ve become a big proponent of using red dots for turkey hunting. They aid in precise aiming at longer distances and help prevent the shooter from looking over the barrel ...
