description The utility model relates to a dual-purpose eyepiece-free microscope using concave lens observation and video imaging. According to the principle of imaging of the concave lens, a sample to be observed is placed in the focal length range of the concave lens, human eyes observe on the imaging light path of the concave lens, an observer can easily observe imaging due to the large observation range,and the situations of eye discomfort, physical fatigue and the like caused by long-time observation can be effectively reduced. Besides, a semi-transparent and semi-reflective spectroscope is adoptedin the light path design, light from a sample is divided into two paths, one path is led to a concave lens, and the eyes of a person can directly observe and image; one path is led to the industrial camera to be imaged on the display, thereby being convenient to use in occasions with cameras and displays; and the two observation methods are combined for use, so that the labor intensity can be reduced, and the working effic
