Problems solved by technology
[0003] When measuring the lens, the existing splicing measurement device places one lens at a time. After the detection is completed, the interferometer needs to be turned off to avoid the lens from reflecting light onto the eyes of the person when the lens is taken, and then the lens is removed. Remove and place another lens to be inspected, low efficiency

Embodiment Construction
[0032] Refer to the attached figure 2 , Figure 4 and Figure 7 , the bottom of the clamp 11 is embedded with a buffer plate 12, the top of the buffer plate 12 is provided with a spring 13, the bottom end of the spring 13 is connected with a tension rope 14, and one end of the tension rope 14 is connected with a gravity ball 15, and the center of the clamp plate 11 is opened There is a vertical cavity, and the gravity ball 15 is located inside the vertical cavity, and the gravity ball 15 pulls the tension rope 14, so that the spring 13 is in a compressed state.
[0033] After the clamping plate 11 followed the rotation of the mounting plate 63 and became vertical, the clamping plate 11 entered the groove, and the groove was sealed, and finally the mounting plate 63 was rotated for half a circle and turned over, and the gravity ball 15 moved To the other end of the vertical cavity, the tension rope 14 is in a relaxed state, the spring 13 recovers, and the spring 13 pushes th...

The invention belongs to the technical field of interference measuring equipment, and particularly relates to a vertical spherical interference splicing measuring device and an adjusting method thereof.The vertical spherical interference splicing measuring device comprises a supporting frame, an interferometer is installed on the front side of the supporting frame, a computer is arranged at the top of the interferometer, a spherical wave conversion mirror is arranged at the bottom of the interferometer, and a three-axis adjusting mechanism is arranged on the front side of the supporting frame; a self-unloading workbench is arranged on the three-axis adjusting mechanism; according to the invention, through the self-unloading workbench, all lenses can be placed at one time, and after the lens at the top is measured, the lenses are deflected, so that the lens at the bottom is exposed, rapid measurement is facilitated, and the measurement efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of interference measurement equipment, in particular to a vertical spherical interference splicing measurement device and an adjustment method thereof. Background technique [0002] With the development of science and technology and industry, modern industry has higher and higher requirements for the precision of optical components, especially in recent years, higher requirements have been put forward for the precision of spherical optical components with large numerical aperture. For the measurement of large numerical aperture spherical optical elements, the lens is divided into multiple areas by a splicing measurement device. After each area is measured, the data is spliced together to complete the measurement of the lens. [0003] When measuring the lens, the existing splicing measurement device places one lens at a time. After the detection is completed, the interferometer needs to be turned off to avo...
