Description

Technical Field

[0001] This utility model mainly relates to the field of ophthalmic diagnostic instrument calibration, specifically to a special metrological verification and calibration bracket for ophthalmic diagnostic instruments. Background Technology

[0002] Ophthalmic diagnostic instruments mainly include slit lamp limiters, focimeters, optometers, and tonometers. The measurement parameters of these instruments need to be periodically verified or calibrated to determine whether their indication errors are within the acceptable range.

[0003] During the operation of specific embodiments, the inventors discovered the following defects: The calibration and verification supports used for ophthalmic diagnostic instruments are mainly designed based on the current instrument measurement observation window position, instrument measurement position, existing instrument support device and human head shape. They do not take into account the problems of small size, difficulty in fixing and adjustment of calibration and verification standards. Calibration standards include standard line rulers, standard lenses, etc. As a result, there are currently no scientifically reasonable dedicated supports and devices for calibration and verification, which is inconvenient for measurement in calibration and verification work.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content
