Here’s why. The compact “luminous capsule” of incandescent and HMI radiates light 360°. Although wasteful from an energy efficiency standpoint, it’s optically useful behind a Fresnel lens. An ...
The 4-solar cell CPV module prototype uses a Fresnel lens to concentrate light onto cells soldered on a transparent glass PCB and protected by lamination layers. The emitter contacts are soldered ...
Pronounced "fraynel zone." The pattern of electromagnetic radiation that is created by a transmitting station from its antenna to receiving antennas. It is in the shape of an ellipsoid, or 3D ...
Meta has announced the Quest 3S, a long-expected headset that fills out the more affordable end of the virtual reality headset lineup. You’ll pay $299.99 for a Quest 3S, compared to $429.99 for ...
