Embodiment Construction
[0020] The specific embodiment and working principle of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0021] See attached figure 1 , a wedge-shaped lens precision axis fixed method, according to the following steps:
[0022] Step 1: Place a standard mirror 2 on the rotary indexing table 3, and set up an autocollimator 1 on one side of the standard mirror 2, such as figure 2 As shown, adjust the posture of the autocollimator 1 so that the crosshair image reflected by the standard mirror 2 to be tested coincides with the inherent self-collimation crosshair of the autocollimator 1, that is, the surface normal of the standard mirror 2 is collimated. straight;
[0023] In this embodiment, the autocollimator 1 adopts the Collapex AC300 digital display photoelectric autocollimator, which has the functions of automatic data collection and storage, and is easy to realize intelligent control. Its main performance inde...
