Abstract

The invention belongs to the technical field of microscopes, and relates to a microscope lighting system based on LED arrays. The microscope lighting system comprises a microscope frame, a fixing device, a connecting device and an electric appliance controller, wherein an ocular lens, a converter, an object lens, an objective table set, a contrast push-pull plate set, a lighting device, a focusing mechanism and a lens wall set are arranged on the microscope frame, and the lighting device comprises an aspherical lens, an LED array lamp set, a PCB and an aperture diaphragm set. The lighting device is fixed into an integral body through the fixing device, and the focal length of the aspherical lens is 8-30mm. The LED array lamp set is arranged on the PCB and situated on a conjugate plane of the object lens incident pupil after passing the aspherical lens, the divergence angles of the LEDs in the LED array lamp set range from 15 to 60 degrees, and the number of the LEDs is no less than 15. The connecting device connects the lighting device on the microscope frame, and the lighting device is connected with the electric appliance controller through the connecting device. Nonuniform illumination and other problems caused by structural defects of a conventional microscope lighting device can be solved.

Description

technical field [0001] The invention belongs to the technical field of microscopes, and in particular relates to a microscope lighting system based on an LED array. Background technique [0002] The microscope optical system includes two parts: the illumination system and the imaging system. The illumination system is a very important part of the microscope. The illumination mode of the illumination system has a very important impact on the imaging system, and it can usually be used to affect the performance of the microscope. But the illumination system is also the least understood part of the microscope. In many cases, a well-designed microscope does not necessarily achieve good imaging quality. In the book "Photography Through the Microscope", John Delly believes that it is provided for academic discussions and exhibitions. 80% to 90% of the photomicrographs in scientific and technical publications have incorrect optical path correction, and the lighting conditions of the...
