引言长春光机所衍射光栅的研究工作是1958年开始的。经二十多年的努力建立了一整套光栅刻划机设计、加工、装调技术,制造了4台三种类型的光栅刻划机,并向国内七个光学仪器厂推广,建立了光栅检验设备及六项光栅性能指标的检验方法。掌握了从近紫外、可见到近、中红外光栅刻划的基本技术。建立了光栅复制工艺。已向国家提供原刻光栅及复制光栅近百个品种,一千余块。近年来,又开展了大光栅机、凹面光栅机构、全息光栅及其它光栅的研究和设计工作。下面就几个方面分别介绍。 Introduction Changchun Institute of optical diffraction grating research work began in 1958. After more than two decades of efforts to establish a set of grating sculler design, processing, loading and adjusting technology, created four sets of three types of grating sculpting machine, and to promote the seven optical instrument factory, the establishment of the grating test Equipment and six grating performance test methods. Mastered from the near UV, can be seen near, the basic technology of infrared grating characterization. Established a grating replication process. Has provided the original engraved grating and copy grating nearly 100 varieties, more than a thousand pieces. In recent years, the research and design of large grating machines, concave grating institutions, holographic gratings and other gratings have also been carried out. Here are a few aspects were introduced.
