31 Μαρ 2021 · Fly’s eye arrays are typically used in pairs along with a condenser lens to provide uniform irradiance at the illumination plane. The first fly’s eye array is often called the "objective array" and the second array, along the optical axis, is called the "field array".
24 Νοε 2022 · The design of fly’s eye homogenizers is very dependent on the source being homogenized. It would be very unusual to find that a design for one source worked for another, unless they were very similar. And the lens arrays are molded.
Field-averaging micro lenses that synthesize highly uniform illumination in coherent EUV optical systems Christopher N. Anderson (1), Patrick P. Naulleau (2), Paul Denham (2), Drew Kemp (2) and Senajith Rekawa (2) CONCLUSIONS •We’ve developed a field-averaging scanning-Fly’s Eye stage enabling non-uniform, high-coherence sources to be
6 Σεπ 2024 · These small lenses are tightly arranged together, forming an array that mimics the structure of compound eyes in insects, especially flies and other insects, hence the name. The design inspiration for compound eye lenses comes from the compound eye mechanism in nature.
10 Ιουν 2019 · Microlens Array system. Principle and design. When light passes through the first row of microlens arrays in the illumination system, the broad beams are divided into several fine beams. These fine beams are imaged on the second row of microlenses, and the uniformity of each fine beam is improved compared with that of the wide one.
refractive freeform lens. The method can be used to design a freeform lens in a fast way (just less than 20 seconds on a common PC). Using an LED as the source, a uniform rectangular form illumination can be gotten through single refractive freeform lens, and with illumination uniformity near to 90%.
1 Μαΐ 2004 · Both illumination system designs of the light pipe and fly's eye lens array are presented using standard optical design software Zemax, including the shaping design of laser source...
