Description

technical field [0001] The invention relates to the technical field of lighting with a miniaturized low-power light source, in particular to an integrated light source device for a microscope objective lens array, which is applied in the field of microscope light sources. Background technique [0002] In the light source system of optical microscope, the irradiated light usually has a Gaussian distribution. The central area of ​​the microscopic field of view has the highest brightness, and the surrounding brightness is low. This uneven illumination problem is reflected in the digital image in the digital microscope. It is the field of full slice imaging of digital pathology. Digital images of multiple microscopic fields of view need to be spliced. Uneven illumination will lead to light and dark fluctuations in the spliced ​​digital pathology images, which must be compensated by digital image brightness adjustment algorithms, otherwise it will cause the diagnostician’s confusi...

Problems solved by technology

However, such a lighting optical structure is complicated, and the use of more lenses brings about an increase in cost, which is not conducive to the miniaturization and cost reduction of the lighting system

[0004] In addition, in order to improve the shortcomings of existing optical microscopes that can only observe one microscopic field of view at a time, and meet the needs of simultaneous microscopic observation of multiple microscopic fields of view, a new type of objective lens array for multi-field imaging is designed. The illumination needs of this new type of objective lens array urgently need to design an integrated light source device for this new type of microscopic objective lens array, and it is necessary to meet the requirements of more uniform illumination for microscopic illumination
