WebThis DOE design includes two diffractive surfaces. The first decreases the coherence of the incident beam and the second surface shapes the beam. Advantages and disadvantages of HH relatively to HM are displayed in below table: This can be illustrated with the figures below: Application example - Optical Setup with MM fiber WebDiffractive Optical Element (DOE) are phase elements that manipulate an input laser beam to various output profiles and shapes, using thin micro-structures embedded within the element. Diffractive optics enables many functions and light manipulations which are not feasible in standard refractive optics.
WebSep 26, 2024 · Each beam shaper is designed for specific use with a unique set of optical system parameters: wavelength, input beam size, working distance, and output spot size. The most rudimentary set-up in a beam shaper application consists of a laser, a diffractive beam shaper element and the surface to be treated. Top-hat beam shaper WebHolo/Or is a TOP-HAT beam shaper and homogenizer in response to the desire to fine-tune output parameters such as shape/spot size and separation/divergence angle when using DOE. We have developed a variable beam expander that is most suitable for DOE products such as multi-spot. Also, in top hat applications where the accuracy of the incident ...
