Top-hat beam
Did you know?
WebA TOP-HAT or flat-top beam shaper is an optical element that mainly applies Diffractive Optical Element (DOE). A diffractive optic (DOE) for converting a Gauss (TEM00) incident laser beam into a spot with a uniform intensity distribution with sharp edges such as circles, rectangles, rectangles, and lines on a particular machined surface. WebA flat-top beam (or top-hat beam) is a light beam (often a transformed laser beam) having an intensity profile which is flat over most of the covered area. This is in contrast to Gaussian beams , for example, where the …
WebA top hat, also known as a stove pipe or snoot, is a device used in theatrical lighting to shield the audience's eyes from the direct source of the light. ... A beam bender is essentially a large adjustable mirror, mounted into the color slot on the front of a lighting fixture. It is designed to allow a fixture to be mounted at right angles to ... Web1. júl 2024 · Thus, converting the spatial beam profile into Bessel or top-hat beam can be considered as another optical solution. For example, He et al. (2024) adopted an axicon and designed a binary phase plate to produce a tailored Bessel beam that facilitated drilling holes with 10 μm diameter in 100 μm thick Silicon with almost taper-free sidewalls.
WebThe top-hat beams are ideally suited for installing floor components in buildings: placing the components between the top-hat beams reduces the storey height and creates more … WebTop-hat beam shapers with passive beam stabilization feature are available for single-mode lasers, especially ultra-short pulse lasers. We also offer beam shaping modules and laser heads with low focus shift and high depth of field for high-power multi-kW lasers. Reflective axicons are also available for high-quality Bessel beam generation.
WebTop-hat beam shaper The top hat beam is used to transform a near-Gaussian incident laser beam into a uniform-intensity (flat) spot of either round, rectangular, square, line, or other shape with sharp edges in a spe-cific work plane. For good quality beam shaper performance, the laser output should be single mode (TEM 00) with an M2 value < 1.3.
