An isometric mesh on the concave of a spherical substrate was formed by latitude line intersection each other,in which latitude lines was generated by a concentric optical scanning method.An optical axis,erection turning spindle,horizontal dividing spindle and a pitching dividing spindle were positioned on the concave center of the spherical substrate in concentric scanning.The concentric error between these spindles with the concave center may bring on the defocus of optical system and the error of the mesh period,but because the ratio of the period error to the period is very small,the latter may be ignored.The theoretical analytical result shows that the line width of mesh is restricted by the dimension of focal spot and the defocus of optical system determines the smallest dimension of focal spot,so the line width of mesh is restricted by the concentric error,i.e.the smaller the concentric error is,the smaller the line width is also.
