Zhejiang Crystal-Optech Co., Ltd. was founded on August 2, 2002, and subsequently listed on the Shenzhen stock exchange on September 19, 2008 (stock code 002571). In 2021, operating revenue reached 38 billion yuan, with year-on-year growth of 18.18%, and the net profit was 442 million yuan .

伟嘉科技践行“成为具有世界一流水平的高科技光电企业”企业愿景，沿着同心多元化发展战略布局，经过20年的发展，成为涉及五大产业板块的研发与制造企业，产品包括光学元器件、生物识别、薄膜光学面板、新型显示、反光材料等。公司下设十余家全资及控股子公司，并参股日本光驰株式会社、宁波基石投资、武汉物易云通、京浜光学、朝歌数码等多家企业。 

Crystal-Optech adheres to strategic deployment of diversified development and strives to become a world class precision optoelectronics technology enterprise. 20 years later, it had developed the largest R&D and manufacturing company covering five industrial sectors namely in optical component, biometrics, thin film optical panels, new displays and reflective materials. There are more than ten wholly-owned subsidiaries with huge investments in in Japan Guangchi Co., Ltd., Ningbo cornerstone investment, Wuhan Wuyi Yuntong, Jingbang optics, Chaoge digital and other enterprises.

公司主导产品光学低通滤波器（OLPF）、红外截止滤光片及组立件（IRCF）和窄带滤光片（NBPF）产销量居全球前列。3D深度成像、光学元器件、增强显示（AR）组件、半导体封装光学元器件、微纳结构加工光学元器件等产品均已应用于全球知名消费电子、汽车电子、安防监控、工业应用企业的产品与服务中。此外，伟嘉科技下属全资子公司江苏夜视丽生产的反光材料多年来在国内保持技术领先地位。 展望未来，随着5G技术的普及和应用，全球光学行业已经迎来一个千载难逢的好时机。伟嘉科技将继续坚持“全球化、技术型、开放合作”的指导方针，坚持“基础经营、战略新业务、生态建设”铁三角经营模式，在薄膜光学元器件、生物识别、薄膜光学面板、AR新型显示、汽车电子、半导体光学等领域继续加大技术研发投入，以智能手机、智能安防、智能家居、智能汽车等为场景，提供世界一流水平光学解决方案，为实现5G全场景智慧生活贡献力量。

        Optical Low Pass Filters (OLPF)), and IR cut Filters (IRCF) and Narrow band  pass filter (NBPF) are among the most commonly used optoelectronics in the world. Many such filters had been applied in leading brands of consumer electronics, automotive electronics, security monitoring, industrial application and service, including 3D deep imaging, optical components, enhanced display (AR) components, semiconductor packaging optical components, micro nano structure processing optical components and etc.. In addition, Zhejiang Yeshili, a wholly-owned subsidiary of Crystal-Optech, has been keeping a leading position in reflective technology in China for many years. Looking forward to the future, a golden opportunity is in front of the global optics industry with the popularization and application of 5G. Crystal-Optech will adhere to the guideline of “globalization, technology-based and open cooperation” and thereby formed the iron triangle operating model of “basic operation, strategic new business and ecological construction”. Meanwhile, it will continually invest heavily in thin film optical components, biometrics, thin film optical panel, AR new display, automotive electronics, semiconductor optics and etc. The world class optical solutions would be proposed to apply in smart phone, smart security, smart homes, smart cars and other sectors, making substantial contributions to the entire 5G architecture and enhancing the entire smart life concept.
