Portable Microscopes and How They Work

Abstract

The invention belongs to the field of microscopes and provides a portable microscope and a working method thereof. Among them, the portable microscope includes a slide holder, which can move in the horizontal and vertical directions; a liquid self-zooming lens, which is arranged above the slide holder; the liquid self-zooming lens includes a magnetic field part and a zoom part, and the zoom part includes a cylindrical The cavity is encapsulated with immiscible transparent liquid, the lower surface of the bottom plate of the cylindrical cavity is attached with a magnetic conduction layer, and nano-magnetic particles with grafted functional groups are deposited on the top of the bottom plate, and the aggregates of nano-magnetic particles The shape changes with the intensity of the magnetic field; the cover plate is provided with a light hole; the cover plate is provided with an image acquisition display terminal, the image acquisition display terminal includes an image acquisition part and a display part, and the image acquisition part is used to pass through the light hole The image collected from the liquid self-variable lens is sent to the display unit for display.

Description

technical field [0001] The invention belongs to the field of microscopes, in particular to a portable microscope and its working method. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In recent years, with the intensification of water eutrophication and global climate change, the scale and frequency of harmful algal blooms have been increasing year by year. Algal blooms have seriously affected aquaculture, tourism, marine ecosystems, and even endangered human health. . Harmful algal blooms are mostly caused by the explosive growth of microscopic phytoplankton, such as red tides and brown tides. By monitoring the types and densities of microscopic phytoplankton in waters, researchers can give early warning of harmful algal blooms and provide data for studying the mechanism of algal blooms, so real-time monitoring of algal blooms is parti...

AI Technical Summary

Problems solved by technology

[0004] The inventor found that the traditional microscope is bulky, complicated to operate, and expensive, so it is inconvenient to carry it to the sea for sampling and monitoring

If the sample is taken back to the laboratory for monitoring, the monitoring results will be affected due to changes in the status of the algae (such as death, proliferation, etc.)

In addition, the current commonly used methods for detecting algae density include cell counting, visible spectrophotometry, chlorophyll α method, and fluorescence spectrophotometry. The density detection of a certain type of algae can be accurately detected, while the cell counting method can accurately detect the density of a certain type of algae, but the operation is complicated, the workload is heavy, the time is long, and the professional level of the detection personnel is high.
