Portable precision digital optical microscope

Abstract

The invention relates to a portable precision digital optical microscope and belongs to the technical field of digital optical microscopes. The micro lens of the digital optical microscope is a plano-convex lens with a short focal length. A CCD image sensor is fixed to an image sensor installing frame. The bottom of the image sensor installing frame is successively in threaded connection with an image sensor installing seat, an upper lens cylinder, a lower lens cylinder, and a lens seat. The bottom of a fine tuning knob is abutted against the top surface of a slide body sliding in a guide body. The top of a tension spring hangs over an upper spring pin fixedly connected with a guide body. The bottom of the tension spring hangs over a lower spring pin fixedly connected with a slide body. An LED lamp assembly, a sample glass slide, the micro lens, and the CCD image sensor are arranged in the same straight line. The digital optical microscope is small in size, light in weight, low in price, good in imaging, easy to establish and carry, capable of wirelessly transmitting pictures and accurately controlling a sample position, accurate in focusing, and especially suitable for being used under rigorous conditions of timely detection and outdoor investigation.

Description

technical field [0001] The invention relates to a portable precision digital optical microscope, belonging to the technical field of digital optical microscopes. Background technique [0002] Light microscopy is a simple, yet essential imaging technique that is applicable and plays an indispensable role in many fields, including medical diagnostics, biological sciences, and materials research. Despite rapid advances in optical imaging, state-of-the-art microscopy modalities still require complex and expensive equipment, which not only makes it difficult to use in harsh conditions such as timely detection and field observation, but also limits their use in laboratories. Microscopes, however, have different requirements in resource-constrained environments. These laboratories need to be cost-effective, compact, lightweight, and reasonably accurate and simple. Therefore, research on simple, cheap and small microscopes has become a trend. Compared with traditional microscopes,...
