Description

Technical Field

[0001] The utility model relates to the technical field of interferometers, and particularly relates to an interferometer for detecting optical lenses. Background Technique

[0002] An interferometer is a general term for a very wide class of experimental techniques. The idea is to use the superposition of waves to obtain the phase information of the waves, so as to obtain the physical quantities concerned in the experiment. Interferometers are not limited to optical interferometers. Interferometers are widely used in precision measurement fields such as astronomical optics, engineering measurement, oceanography, seismology, spectral analysis, quantum physics experiments, remote sensing, and radar.

[0003] For example, the publication number is CN208076131U, and the Chinese authorized patent name is an interferometer for detecting optical lenses, including: a bottom plate, an upper end of the bottom plate is fixedly installed with a placement plate, an upper end of the placement plate is fixedly installed with a machine body, a storage groove is opened at the upper end of the placement plate, and gears are arranged around the inner cavity of the placement plate, and one end of the gear extends to the outside of the placement plate. For this interferometer for detecting optical lenses, through the combined setting of the placement plate, the machine body, the storage groove, the gears, the connecting rods, the folding film, the elliptical disc, the fixing rods, the single-sided racks and the friction plates, when the lens interferometer is in use, generally the lens is placed on the placement plate for detection. This detection method cannot effectively fix the lens. If the lens is displaced, the lens may be scratched due to the friction between the lens and the plate surface.

[0004] However, when the existing interferometer fixes the optical lens, due to the rigidity of the fixing method, it is easy to damage the optical lens; therefore, it does not meet the existing requirements. For this reason, we propose an interferometer for detecting optical lenses. Content of the Utility Model

[0007] It further includes:

[0008] A placement area, which is installed inside the middle position of the upper end face of the interferometer body. The upper end face of the interferometer body is provided with rotating rods, and there are four rotating rods. All four rotating rods are rotationally connected to the upper end face of the interferometer body through electric rotating shafts;

[0009] An air pump, which is installed on the upper end face of one end of the four rotating rods. There are four air pumps. Soft air bags are arranged below the four rotating rods, and the upper side of the soft air bag is heat-melted and connected to the lower side of the rotating rod. A first port is arranged on one side of the air pump, and a second port is arranged at the lower end of the air pump. One end of the second port penetrates through the rotating rod and extends into the interior of the soft air bag.
