Fluorescence microscope capable of controlling light source by use of touch screen system

Abstract

The invention discloses a fluorescence microscope capable of controlling a light source by use of a touch screen system. The fluorescence microscope comprises a microscope host unit using an infinite multi-color difference correction optical system, a fluorescence objective lens using high-resolution infinite plan high numerical aperture, a tri-ocular observation system provided with a digital single lens reflex camera, a fluorescence color filter group with a transmittance of 90% to 95%, an LED (light emitting diode) white light source as the specimen background light source, and an LED fluorescence excitation light source for emitting an excited light to the specimen, wherein the fluorescence objective lens, the tri-ocular observation system, the fluorescence color filter group, the LED white light source and the LED fluorescence excitation light source are arranged on the microscope host unit; and the microscope host unit is also provided with a touch screen for controlling the brightness of the LED white light source and the LED fluorescence excitation light source. The touch screen as the light source control unit of the fluorescence microscope provided by the invention is the simplest, the most convenient and natural man-machine interaction manner at present.

Description

technical field [0001] The invention relates to an optical microscope, in particular to a fluorescent microscope which uses a touch screen system to control a light source for observing the fluorescence emitted by a specimen. Background technique [0002] A fluorescence microscope, which observes fluorescence from a specimen on it, is a type of microscope. It is a special tool for fluorescence detection and is a high-tech instrument. Fluorescence microscope uses ultraviolet light as the light source to irradiate the object under inspection to make it emit fluorescence, and then observe the shape and location of the object under the microscope. Fluorescence microscopy is used to study the absorption and transportation of substances in cells, the distribution and localization of chemical substances, etc. Some substances in cells, such as chlorophyll, can fluoresce after being irradiated by ultraviolet rays; although some substances themselves cannot fluoresce, they can also ...

AI Technical Summary

Problems solved by technology

[0007] Traditional fluorescent light sources also use halogen lamps, xenon lamps, etc. for lighting, but they all have obvious disadvantages: short life, frequent replacement of bulbs; need to wait for a period of time to warm up each time they are used; high energy consumption; lamps containing lead and mercury Substances that pollute the environment and are harmful to users

However, there are disadvantages in mechanical adjustment: for example, the adjustment amount is not detailed enough, not precise enough, the operation is not intelligent enough, and it is inconvenient, etc.
