福建福晶科技股份有限公司“一种远心场镜模组和远心光学系统”专利公布

Core Viewpoint - Fujian Fuzhijng Technology Co., Ltd. has recently published a patent application for a "telecentric field lens module and telecentric optical system," which pertains to the field of high-energy laser processing [1] Summary by Relevant Sections - Patent Details - The patent application describes a telecentric field lens module that includes five lenses arranged sequentially from the object side to the image side. The first and fifth lenses have negative focal lengths, while the second, third, and fourth lenses have positive focal lengths [1] - Aspheric surfaces are incorporated on at least the third and fifth lenses to correct aberrations in the focused light spot projected on the image side [1] - Technical Advantages - The telecentric field lens module is designed to eliminate chromatic aberration in ultrafast lasers, such as femtosecond lasers, which often experience pulse broadening. The output laser spot exhibits improved roundness and uniformity, meeting various processing requirements for femtosecond lasers [1]
