| Abstract: | A method to adjust the Cassegrain reflector was introduced.The focus of the parallel beam reflected by the hyperbolic mirror would move when its optical axis was not coincided with the mechanical axis.First,the hyperbolic mirror was aligned to make its optical axis coincided with the mechanical axis.Then,a cross reticle was put at the focus of the Cassegrain reflector.The beam was reflected by the secondary mirror and the primary mirror,then received by a internal focusing telescope.The beam would not move ... |
