摘要
现有的光谱共焦显微镜色散物镜的量程大多在数毫米量级,为满足工业测量领域对大量程线性色散物镜的需求,文章从线性色散物镜设计原理出发,采用高性价比环境友好型光学玻璃,设计了一款仅由五片全球面镜片组成的超大量程线性色散物镜。设计结果表明,该物镜在400~700nm波长范围内的轴向色散达到30.44mm,且色散-波长线性度高于0.99,具有优异的线性关系,理论分辨率可以达到2.034μm。
The measuring range of most existing dispersive objective lenses for the chromatic confocal microscopy are on the order of several millimeters.In order to meet the demand for large range linear dispersive objective in the industrial measurement field,a linear dispersive objective with a super large range was designed based on the design principle of linear dispersive objective.It is composed of only five spherical lenses,all of which are made of cost-effective and environmentally friendly optical glasses.The design results show that the axial dispersion of the objective lens is 30.44mm in the wavelength range of 400~700nm,and the dispersion-wavelength linearity is higher than 0.99,which has an excellent linear relationship,and the theoretical resolution can reach 2.034μm.
