Visual slit-lamp microscope correction device

Abstract

The invention discloses a visual slit-lamp microscope correction device which comprises a collimator, a microscope large object lens module, a microscope small object lens module, a flat base and an image collection and analysis module. The collimator, the microscope large object lens module and the microscope small object lens module are mounted above the flat base, and the image collection and analysis module is positioned on the left side of the collimator. Through the above mode, by the visual slit-lamp microscope correction device, correction can be realized by using human eyes, and correction can be assisted by collecting, analyzing and comparing images; by using the device to correct a slit-lamp microscope, correction accuracy can be improved, correction errors can be reduced; the human eyes can be liberated to some extent, so that labor intensity is lowered, and working efficiency is improved.

Description

technical field [0001] The invention relates to the field of photoelectric imaging, in particular to a visualization correction device for a slit lamp microscope. Background technique [0002] As a kind of ophthalmological examination instrument, the slit lamp microscope should have clear and bright observation effect, which is helpful for doctors to make a quick and accurate judgment on the condition. High-standard slit lamp microscope calibration device, the traditional slit lamp microscope calibration method adopts the eyepiece observation method, that is, put the microscope to be calibrated on the calibration instrument, and observe the alignment of the optical reticle in the instrument through the eyepiece on the instrument. If the alignment of the reticle cannot meet the calibration standard, adjust the optical lens in the microscope to align the center of the reticle. [0003] The traditional calibration method relies on the human eye to observe the alignment of the ...

Problems solved by technology

[0003] The traditional calibration method relies on the human eye to observe the alignment of the reticle. Since the human eye observation inevitably has deviations, and the microscope is under low magnification, it is difficult for the human eye to distinguish the clearest position. Therefore, the microscope calibrated in this way has precision. not high problem

Moreover, observing the microscope for a long time will cause people's visual fatigue and further reduce the accuracy of the correction, so the traditional correction method is in urgent need of improvement
