Following research at Sheffield-based LED packaging firm Litecool, narrow beam angles from LED packages without secondary optics or reflectors look closer. The proof-of-concept device produced a beam ...

Ordinarily, headlamp users have to manually switch the angle of their device, depending on what they're doing. The Adaptev Headlamp isn't like that, in that it automatically switches beam angles based ...

Just buy one with the right beam angle, and you are off. Right? Well maybe, but probably not. Because there are a few more things to think about before you can be pretty sure that what you buy will do ...

The light intensity curves for LEDs, regardless of whether they are collimated with a lens or reflectors, follow a bell shaped curve (often referred to as a “Lambertian“ curve). The 50% intensity ...

The CoveWash linear LED lighting system provides even illumination with user-specifiable beam angles. It is intended for cove (recessed) and other indirect indoor lighting applications in commercial ...

Beams of light polarized into spirals have been used by scientists in the UK to create intricate patterns on the surface of metals. This is the first time that these “logarithmic spirals” have been ...

Ion beam expertise is critical to delivering the manufacturing tolerance required for these gratings. Oxford Instruments Plasma Technology has developed a technology to allow optical designers to ...

We’ve made another step forward in building real-life tractor beams. Turns out that the trick is in the angle of the beam, and Star Trek did a pretty good job of representing what a real tractor beam ...

This is the second article of our three-part series on phased array antenna patterns. In Part 1, we introduced the phased array steering concept and looked at the influencers on array gain. In Part 2, ...
