Artificial keratoscope column optical performance detector

Abstract

The invention provides an artificial keratoscope column optical performance detector.The artificial keratoscope column optical performance detector comprises a light source, a light extension module, a measuring plate, a parallel light module and a measuring module.The light source, the light extension module, the measuring plate, the parallel light module, a simulation eye and the measuring module are sequentially arranged in the light beam irradiation direction, and the measuring plate is arranged on a focal plane of the parallel light module.The simulation eye is used for installing a keratoscope column.The light extension module is used for extending and paralleling the diameter of the light beam emitted by the light source and irradiating the parallel light beam onto the measuring plate.The parallel light module is used for collimating the light beam and irradiating the collimated light beam onto the keratoscope column installed on the simulation eye.The measuring plate and the measuring module are matched to measure the optical performance of the keratoscope column.By the adoption of the structure, a doctor can detect the optical performance of the artificial keratoscope column to be installed before an operation, and then can judge whether the keratoscope column meets the requirements of patients or not; if not, the keratoscope column can be corrected in advance, and therefore the pains caused by many times of operations on patients are avoided.

Description

technical field [0001] The invention relates to the technical field of optical performance detection, in particular to an optical performance detector of an artificial corneal lens column. Background technique [0002] The artificial cornea is a product made of medical polymer materials similar to the human cornea. The artificial cornea generally includes two parts: a lens column and a bracket. Among them, the lens column is made of a transparent material with excellent optical properties and stable physical and chemical properties. Lesioned opacity of the cornea that obstructs the optical pathways of the eye; the primary optical properties of the mirror column include optical power and resolution. [0003] After the patient is installed with an artificial cornea, the optical performance of the lens column determines the quality of his visual function to a large extent. Therefore, before the operation, it is necessary to check the optical power and resolution The rate is te...
