Abstract

The invention discloses a microcirculation imaging lens. The microcirculation imaging lens comprises an object surface, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixthlens, a seventh lens, an eighth lens, a diaphragm, a ninth lens, and an image surface which are sequentially distributed from an object side to an image side along an optical axis; the object side surfaces and image side surfaces of the first lens and the second lens are planar; the third lens and the fourth lens are cemented to form a first cemented lens group; the image side surface of the thirdlens is cemented to the object side surface of the fourth lens; the fifth lens and the sixth lens are cemented to form a second cemented lens group; the image side surface of the fifth lens is cemented to the object side surface of the sixth lens; the seventh lens and the eight lens are cemented to a third cemented lens group; the image side surface of the seventh lens is cemented to the object side surface of the eighth lens; and the ninth lens is a plano-convex lens. The imaging clarity of the imaging lens of the invention can be improved; and the imaging lens of the invention can meet therequirement of sublingual microcirculation observation.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to a microcirculation imaging lens. Background technique [0002] The blood circulation between arterioles and venules in the human body is called microcirculation, which is the most basic unit of human blood circulation and the place where blood and tissues exchange materials. The blood flow of microcirculation directly reflects the metabolism of human organs If the microcirculation of the human body is obstructed, it will have a greater impact on the physiological functions of tissues and organs. When pulmonary edema, shock, etc. occur, the state of human microcirculation will change greatly. Therefore, monitoring and observing human microcirculation has very important clinical significance for medical diagnosis. [0003] In the prior art, in order to observe the microcirculation of the human body, a large and bulky microscope is usually used, which can only observe the m...
