Monocular with microscopic and telescopic functions and design method thereof

Abstract

The invention discloses a monocular with microscopic and telescopic functions and a design method thereof, and relates to the technical field of optical stationery. The monocular comprises an outer tube which sleeves an inner tube matched with the outer tube, an objective lens sleeve is connected to the left end spiral of the outer tube, an objective lens is arranged in the objective lens sleeve,a first inverting lens is arranged in the inner tube, the first inverting lens is located at the left end of the inner tube, a first support tube is arranged in the inner tube, and the left side faceof the first support tube makes contact with the right side face of the first inverting lens. According to the monocular with the microscopic and telescopic functions, by arranging the objective lens,under the action of the first inverting lens and a second inverting lens, by adjusting the distance between the objective lens and the first inverting lens, the image erecting telescoping or image erecting microscope effect can be achieved, the problem that for a traditional monocular with the microscopic and telescopic functions, an image is inverted in the microscopic state is solved, under theaction of four lenses, the telescopic and microscopic effects can be achieved, and the structure is simple.

Description

Technical field [0001] The invention relates to the technical field of optical cultural and educational articles, in particular to a monocular lens with both microscopic and telephoto functions. Background technique [0002] A microscope is a commonly used optical instrument for observing tiny objects. A telescope is a commonly used optical instrument for observing distant objects. In the current market, a microscope and a telescope are two different instruments. Few of them can be used as microscopes. It can also be used as a telescope. [0003] Application number: 201710080310.2 published an optical system with both telephoto and microscopy functions. A total of 8 lenses are used and the production cost is relatively high. The telephoto function corresponds to the upright image, and the microscopy function corresponds to the inverted image. Image, inconvenient to identify small objects, application number: 201610935535.7 announced a portable multi-function telephoto / microscope d...

Problems solved by technology

[0004] The purpose of the present invention is to make up for the deficiencies in the prior art, and to provide a monocular with both microscopic and telescopic functions and a design method thereof, which has an upright image no matter whether it is a microscopic function or a telescopic function. , which is consistent with the observed object and easy to identify, and the device has the advantages of simple structure, low cost, convenient use, and good imaging quality, which solves the problem that the existing monoculars with both microscopic and telescopic functions stand upside down in the microscopic state imaging, and its overall structure is complex
