Most laser sources produce Gaussian beams that diverge as they propagate. This natural spreading limits their effectiveness in applications that require light to remain concentrated over long ...

Optical Surfaces Ltd has received an order from Armstrong Optical, a leading UK supplier of optical metrology instruments, to supply high specification transmission and reference flats for a custom ...

A Gaussian beam is transformed into a Bessel beam using a binary axicon and then reshaped by a flat multilevel diffractive lens into a micron-sized optical bottle beam, enabling long-distance ...
