Intelligent type multi-wavelength LED fluorescent microscope light source

Abstract

The invention relates to an intelligent type multi-wavelength LED fluorescent microscope light source. The light source is composed of a switch, an electro-motor, an LED light emitting chip, a potentionmeter, a movable resistor, a single chip microcomputer, a power source line port, a USB output port, a diverging lens, a focusing lens, an optical fiber port, a control panel, a shell and an array fixator, the light source is high in purity, good in uniformity and high in output strength, and can be controlled through a computer. Compared with a product with the same kind, the intelligent type multi-wavelength LED fluorescent microscope light source has the advantages of being low in energy consumption, long in service life, much in wavelength, high in luminous intensity, good in purity, small in size and the like; compared with other laser devices, the cost is low and a light filter is not needed; besides, the intelligent type multi-wavelength LED fluorescent microscope light source can be controlled by the computer, and the intellectualized degree is high. Due to the fact that multiple kinds of monochromatic wavelength light can be output without the light filter, the production is simple, the operation is simple, the cost is low, the mass production can be easily achieved, and thus the intelligent type multi-wavelength LED fluorescent microscope light source has a good market prospect.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a device that uses LED light-emitting chips to emit light sources of different wavelengths. Background technique [0002] Fluorescence microscopy is a microscopic optical observation technology that uses light of a specific wavelength to irradiate the object under inspection to produce fluorescence for microscopic inspection. In recent years, with the continuous development of fluorescence microscopy technology, a new generation of fluorescence microscopes such as total internal reflection, laser confocal and super-resolution have gradually emerged, which play an irreplaceable role in the research of life science, environmental science and chemistry. effect. Fluorescence excitation light sources are the most important components of fluorescence microscopes, commonly including high-pressure mercury lamps, xenon lamps, LED lamps and lasers. However, the wavelength of the ...
