Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of external mirror, concretely is an external mirror tube with protective structure. BACKGROUND

[0002] Tube lens is used in the microscope mirror body and objective lens, the two are combined to correct the aberration of objective lens, and the field of view of objective lens is quite wide, which is about 40% wider than the field of view of traditional objective lens. Binocular tubes or binocular phototubes with photo tubes are used to place ocular lenses and photo devices. In order to facilitate observation, the tube is made with a certain inclination angle (30° or 45°), and has pupil distance adjusting device, which can be adjusted within 55° to 75° to adapt to the pupil distance of different users. Binocular tubes with photo tubes generally have a light beam distribution prism pull rod on the right side. When it is pushed in, only observation is performed. When it is pulled out, observation and photography are performed simultaneously. Ocular lens is an optical component that magnifies the image formed by the objective lens. The total magnification of the microscope is usually the product of the magnification of the objective lens and the ocular lens. In order to facilitate different vision people to take microphotographs clearly, some ocular lenses are designed to be adjustable. In order to make the microscope have the maximum effective magnification and the highest resolution, the ocular lens must be reasonably selected. So far, due to the restriction of optical law, the maximum effective magnification of optical microscope is 1250-1300 times. 10x ocular lens is the most commonly used and necessary ocular lens.
