Microscopic lens for miniature microscopic image acquisition device

Abstract

The invention provides a microscope lens for a miniature microscopic image acquisition device. The microscope lens comprises a first cemented lens, a second cemented lens, a plano-convex lens and a second positive meniscus lens which are sequentially arranged from the pupil plane of the camera; the first cemented lens is a biconcave lens, and the second cemented lens is a biconvex lens. According to the technical scheme, on the premise that the size is small and exquisite, the quality of collected images can be improved, the focusing range can be enlarged, the influence of dispersion on the image quality can be reduced through the arranged first cemented lens and the arranged second cemented lens, the number of scanned images of one slide can be reduced to 768 through tests, the collection efficiency is greatly improved, and the data volume of the images is also greatly reduced. And subsequent cloud processing procedures are facilitated.

Description

technical field [0001] The invention relates to the field of image acquisition, in particular to a microscope lens used for a microscopic image acquisition device. Background technique [0002] Chinese patent document CN110879999A describes a mobile phone-based miniature microscopic image acquisition device and image splicing and recognition methods. The acquisition device includes a support, a mobile phone fixing platform is arranged on the support, and a microscope lens is arranged under the camera of the mobile phone. There is a slide holder under the microscope lens, and an illumination light source is arranged under the slide holder. The slide holder and the microscope lens perform scanning movements along the X and Y axes, so that the image of the slide is collected to the mobile phone. Inside, the images of slide samples collected in the mobile phone can be stitched and identified, and the images can be uploaded to the cloud for processing by AI on the cloud, greatly ...

AI Technical Summary

Problems solved by technology

The problem with the above-mentioned technical solution is that the mobile phone camera or camera module has the characteristics of fixed focus and fixed aperture, and the focus range is small. Among the images obtained by scanning, each image scanned by each step can only obtain a relatively small amount of time. In a small range, images in other out-of-focus ranges cannot be used for image diagnosis and recognition due to insufficient clarity, resulting in an increase in the number of images to be scanned and an increase in the amount of data processing
