Description

Portable monocular telescope with microspur function

Technical Field

The utility model relates to physics, in particular to a portable monocular telescope with a micro-distance function, which is used for observing remote objects and is specially designed for use.

Background

A monocular telescope is an optical instrument for observing the distant object by magnifying the small field angle of the distant object by a certain multiplying factor to make it have a larger field angle in the image space and make the object which can not be seen or distinguished by naked eyes become clear.

The monocular in the prior art usually designs the focusing barrel to adjust the focal length, and designs and manufactures the monocular of different models independently in the light path design process, thus greatly increasing the production cost and the production time.

Disclosure of Invention

In order to realize the technical purpose, the utility model adopts the following technical scheme:

the utility model provides a portable monocular telescope of taking microspur function, including the mirror body, the inside objective that has set gradually from the object space to the image space of mirror body, half pentaprism, roof prism, the first battery of lens of eyepiece, eyepiece second lens, objective is that cemented lens is formed by two different materials veneer, the objective left side is the convex surface, the objective right side is the horizontal plane, the first cemented lens of eyepiece is formed by two different materials veneer, the first cemented lens left side of eyepiece is the horizontal plane, the first cemented lens right side of objective is the convex surface, eyepiece second lens left side is the convex surface, eyepiece second lens right side is the horizontal plane, objective back-and-forth movement during focusing, guarantee the farthest focusing distance infinity, nearest focusing distance is within 0.25m, contain 4X12, 6X18, the three specification product of 8X24, the exit pupil diameter is 3 mm.

As a further improvement of the utility model, the half pentaprism that the three specification product of 4X12, 6X18, 8X24 adopted, roof prism, the first battery of lens of eyepiece, eyepiece second lens are unified size, can increase the commonality of part like this, reduce part organization and product assembly cost.

As a further improvement of the utility model, the front end of the lens body objective lens is provided with a magnifying lens, and the magnifying lens and the lens body adopt the screw-thread fit to form a microscope with different multiplying powers.

The utility model has the advantages that:

1. the utility model comprises three products with the specifications of 4X12, 6X18 and 8X24, and the diameter of the exit pupil is 3 mm;

2. the three specifications of the product eyepiece group and the prism group are the same, so that the universality of parts can be increased, the cost is reduced, and the objective lenses are double-cemented lenses;

3. the objective lens moves forwards and backwards during focusing, so that the farthest focusing distance is ensured to be infinite, and the closest focusing distance is within 0.25m (micro distance);

4. uniform threads are reserved on the objective frame, so that each product can be connected with a magnifying lens with the same threaded interface to be combined into a microscope with different magnifications for use;

5. a double-cemented lens with the same objective lens of 8X24 is inverted and then is provided with a corresponding structural part to be used as a standard magnifier, a threaded interface which is the same as three products is structurally reserved, and the double-cemented lens can be connected with products of three specifications to be combined into a microscope with different multiplying powers for use.
