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 ...

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 ...

Beam steering is an important factor in LIDAR, microscopy, telescopes, and optical wireless communications. In each of these areas, there is a need for a large sensing range using components with ...

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 ...

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, ...

In Part 1, we introduced the phased array concept, beam steering and array gain. In Part 2, we presented the concept of grating lobes and beam squint. In this section, we begin with a discussion of ...
