1、 Purpose:

The digital research-oriented upright fluorescence microscope utilizes fluorescence microscopy technology and is equipped with four excitation groups. It adopts an infinite flat field achromatic objective lens and a large field eyepiece, with clear optical system imaging and a wide field of view. Observing the fluorescence phenomenon of specimens under the microscope has extremely high sensitivity, and can clearly observe and identify chromosome specimens that are difficult to observe with ordinary microscopy techniques. As a research method or experimental tool, it is widely used in technical fields such as biology and medicine. The falling light fluorescence microscope is suitable for fluorescence microscopy and bright field observation, and is an ideal instrument for research in biology, cytology, oncology, genetics, immunology, and other fields. Can be used by scientific research, universities, medical and epidemic prevention departments.
