Device for testing color rendering performance of eye ground laser therapeutic instrument lighting system

Abstract

The invention provides a device for testing the color rendering performance of an eye ground laser therapeutic instrument lighting system, and mainly aims to solve the problems that in the prior art, when the color rendering performance of the eye ground laser therapeutic instrument lighting system is tested, steps are complex and efficiency is low. The device is characterized in that a laser therapeutic instrument lighting system simple assembly is fixedly connected with a CCD image acquisition assembly or a fiber optical spectrometer acquisition and processing assembly, optical filters comprise the first optical filter and the second optical filter, the first optical filter is located between a right angle reflecting prism and a slit lamp microscope objective lens and perpendicular to the direction of the slit lamp microscope objective lens, and the second optical filter is arranged between the right angle reflecting prism and a model eye device. The slit lamp microscope objective lens, the first optical filter, the right angle reflecting prism, the second optical filter and the model eye device are located in a same optical path. The device for testing the color rendering performance of the eye ground laser therapeutic instrument lighting system can qualitatively and quantitatively test the color rendering performance of the eye ground laser therapeutic instrument lighting system respectively, and the system is simple and compact in structure and convenient and quick to assemble.

Description

technical field [0001] The invention relates to a detection device, in particular to a device for testing the color rendering performance of the lighting system of a fundus laser treatment instrument. Background technique [0002] The fundus laser treatment instrument uses laser photocoagulation technology to treat retinal breaks and retinal detachment, macular edema, choroidal neovascularization, serous chorioretinopathy and other fundus diseases. It is currently the most important instrument for the treatment of fundus diseases. The fundus laser treatment instrument needs to add a functional filter in the observation light path of the slit lamp microscope to prevent the reflected and scattered treatment laser from entering the eyes of the observer (doctor), while ensuring that the observer (doctor) can see clearly To and can distinguish the local tissue of the patient's fundus. At present, the main problem of the fundus laser therapy instrument is the color deviation of t...
