Problems solved by technology

[0002] At present, the traditional manual operation of the domestic lens meter is still the main method. It is cumbersome, time-consuming and labor-intensive to find the optical center of the lens and the positioning, and the cumulative measurement error is relatively large. If the measurement is not good, it will also affect the patient. Therefore, Looking forward to the smart computer focimeter

Abstract

The invention relates to an automatic detection focimeter and a detection method. The automatic detection focimeter includes a drive mechanism, a lens frame fixing mechanism and a rack. The drive mechanism is fixed on the rack. The lens frame fixing mechanism is fixed on the front end of the drive mechanism. An optical source device with an optical source plate, a micropore plate device and a lens barrel is mounted on the drive mechanism. The optical source device is located right above a CCD board fixing seat. The CCD plate fixing seat with a CCD image sensor is mounted on the rack. A Hartmann grating lens mount with a Hartmann grating is connected right above the CCD board fixing seat. A lens holder is connected right above the Hartmann grating lens mount. The centers of the optical source device, the lens holder, the Hartmann grating lens mount and the CCD image sensor are on the same center line in the detection process. The automatic detection focimeter and the detection method in the invention has the advantages of saving time and effort and accurately and normatively performing the lens optical center detection.

Description

technical field [0001] The invention belongs to the technical field of focal length meters, and in particular relates to an automatic detection focal length meter and a detection method. Background technique [0002] At present, the traditional manual operation of the domestic lens meter is still the main method. It is cumbersome, time-consuming and labor-intensive to find the optical center of the lens and the positioning, and the cumulative measurement error is relatively large. If the measurement is not good, it will also affect the patient. Therefore, Looking forward to the smart computer lens meter. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide an automatic detection lens meter and detection method that saves time and effort, and can accurately and standardly complete the detection of the optical center of the lens. [0004] The object of the present invention is accomplished thro...
