Researchers have been able to combine fluorescence observation methods with a microscope equipped with a high numerical aperture objective. With the emergence of biological specific fluorescent protein (such as green fluorescent protein, GFP), fluorescent observation also began to appear in stereo microscope.

The new LED is used as the light source in the illuminator for the observation of falling emission fluorescence microscope, which provides high quality and stable fluorescent lighting, far superior to the traditional mercury lamp lighting. In addition, multi band led light source is optional, and the brightness of each LED can be controlled, which can realize multi wavelength selective excitation, convenient and efficient.

Fungi are eukaryotes. According to their growth characteristics and morphological differences, fungi can be simply divided into yeast, fungi and mushrooms (mushrooms). Among them, there are about 300 kinds of pathogenic fungi for human, and almost all of the pathogenic fungi of medical significance are molds.

With the advent of high-power LED lights, it brings a new choice for the light source of higher education instruments and scientific research instruments. Especially in the field of fluorescent observation application, LED lamp has the characteristics of good monochromatic, no ultraviolet, infrared radiation, stable color temperature, long service life, no waiting time, and continuous brightness adjustment, gradually replacing the traditional mercury lamp, xenon lamp, halogen lamp and other light sources.

Due to the limitation of chip technology, all popular mainstream vision chips (CCD, CMOS, EMCCD, etc.) have to choose between high speed full frame, high quantum efficiency, low noise, high dynamic range and other parameters. Therefore, the traditional research cameras based on these chips are often unable to meet the requirements of customers alone, and for some demanding special fields. Now, the emergence of SCMOS chip is beginning to solve these problems.
