Problems solved by technology

As the observed object gets closer, the position of the target image in the left and right fields of view begins to shift toward the middle, resulting in the inability of the two images to overlap, and the two apertures gradually do not overlap, which affects the observation effect

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] Theoretically, the objective lens always moves inward, but due to the phenomenon of large and small object distances, it is no problem to move inward in the middle. The two optical axes and the central axis are in the same plane, but when adjusted to large and small object distances , the two planes formed by the two optical axes and the central axis have a certain angle, but due to the difficulty in realizing the structure (difficult to realize the angle formed by compensation), they always rotate inward around the central axis when changing, so in When it changes, it is not a change in the vertical plane, but a certain angle upward or downward, and its change efficiency is decomposed. The inward rotation is its change amount multiplied by the cos value. Since the angle is small, cos is close to 1. Therefore, the impact of the inward movement can be i...

Abstract

The invention relates to an adjusting method of a micro-telescope, which realizes the close observation through the displacement adjustment or the common adjustment of the displacement and the angle. The adjusting method is mainly applicable to the field of the binocular telescope. Compared with the conventional binocular telescope, the distance observation is not different, but a very close object can be clearly seen when in the close observation; moreover, the overlapping of the left and the right viewing field rings still can be seen, so the observation effect is improved. The adjusting method is not only applicable to the binocular telescope products of all types, but also can be applicable to the optical instruments of the close binocular observation, and the object in a distance of 0.3 to 0.4 m can be observed. The telescope can be used for the outdoor view for observing the insects. Besides being used as an ordinary telescope, the telescope is also suitable for being used as a popular science teaching aid of the adolescent and as an observation instrument for the insect amateur or the outdoor sports amateur. The telescope has promising market prospect.

Description

technical field [0001] The invention belongs to optical instruments, in particular to a method for adjusting a macro-type telescope. Background technique [0002] Conventional binoculars, when adjusting the image plane, the objective lens frame slides back and forth against the straight guide tube. Use a telescope to observe the target. When the telescope observes an object at infinity, the optical axes of the two lens tubes are parallel, and the light barriers seen by the two eyes coincide, so the objective lens frame guide tubes of the conventional telescope are parallel. As the observed object gets closer, the position of the image of the target in the left and right fields of view begins to shift toward the middle, resulting in the inability of the two images to overlap, and the gradual misalignment of the two apertures, which affects the observation effect. The larger the distance between the two objective lenses, the greater the impact of the non-coincidence of the tw...
