Phase Type Computer Generated Hologram

Ningbo Zhixing Optical Technology Co., Ltd. is a technology-driven enterprise that specializes in the research and development of optical devices. The company provides a full-process solution for computational holograms, from optical design and processing file coding to semiconductor processing, inspection error analysis, and result calibration. With a delivery time of only 1 to 2 weeks and competitive pricing, Zhixing Optics offers a distinct advantage in the market. In terms of calibration plates, the company has extensive experience in material processing, coating, semiconductor processing, precision cutting, and reliability testing, providing comprehensive and professional services for discerning clients. The crafting process for Zhixing Optics begins with drawing a mask reticle layout file in GDS format, which is recognizable by the generation device. The layout file is read by a maskless lithography machine and exposed non-contact to the blank reticle with glue. The required pattern area is then illuminated, causing the photoresist to undergo a photochemical reaction in that area. After developing and fixing the photoresist, the exposed chromium layer is etched with a chromium etching solution to form a light-transmitting area. The resulting opaque area is formed by protecting the layer with photoresist, creating pattern structures with different light transmittances on the reticle. Finally, any remaining photoresist layer is removed, and the reticle is cleaned before use. The core R&D team of Ningbo Zhixing Optical Technology Co., Ltd. comprises graduates from prestigious optoelectronic institutions such as Changchun Institute of Optics and Mechanics, Zhejiang University, and Beijing Institute of Technology, among others. The team has independent aspheric inspection tools (computational hologram, CGH) and can complete optical system design, aspheric surface processing, aspheric inspection tool production, and machine vision calibration board development to meet customer needs. The company's aspheric inspection tools boast intellectual property rights, breaking the monopoly of foreign counterparts in this technology. With a focus on long-term cooperation, Ningbo Zhixing Optical Technology Co., Ltd. has established partnerships with many well-known enterprises at home and abroad to develop calibration boards.
