Focused flat-top light shaper is a composite Phase Optics element that integrates flat-top shaping and focusing functions. By designing a specific Phase distribution, it simultaneously modulates the incident beam: one is to convert the non-uniform light field into a flat-top distribution to ensure uniform light intensity in the spot; the other is to give the beam focusing Phase so that the flat-top light is accurately focused at the specified axial position. This composite function can avoid the complexity of multi-component combination, has the characteristics of high integration and low energy loss, and is suitable for Laser processing, lithography and other scenes that need to focus the spot evenly, and improve the efficiency and accuracy of the Optics system.

Flat-top light shaper is a kind of Optics element that can convert the non-uniform light field such as Gaussian distribution of incident beam into flat-top distribution. It applies differential Phase compensation to different areas of the beam through specific micro-nano structure or Phase modulation, so that the output spot has uniform light intensity distribution and steep edges within a certain range. Compared with traditional devices, it can precisely control the size and uniformity of the flat-top area, has the characteristics of high conversion efficiency and low loss, and is widely used in Laser material processing, lithography, medical Laser and other fields, improving the efficiency of light energy utilization and the consistency of the effect.
