Description

Technical Field

[0001] The invention relates to the technical field of microscopes, and in particular to a multiple fluorescence microscope. Background Art

[0002] Fluorescence microscope is a microscope designed for biology, medicine and other fields. It has the characteristics of high definition, high sensitivity and long life. It uses advanced fluorescence technology to clearly observe fluorescent labeled samples and provide reliable observation and analysis tools for scientific researchers. The light source uses LED light source. The LED light source has a long service life of up to 20,000 hours. At the same time, LED light source is a cold light source, which causes less damage to the sample and generates less heat when used. It is safer and more convenient. The startup and shutdown time of LED light is very short, and it can be used immediately without preheating. This enables the fluorescence microscope to enter the working state more quickly and improves the experimental efficiency. The fluorescence module contains six sets of filters: 1-DAPI channel, 2-TYR480 channel, 3-TYR520 channel, 4-TYR570 channel, 5-TYR620 channel, and 6-TYR690 channel;
