Abstract
The invention relates to the technical field of optical instruments, in particular to pupil distance self-adaptive observing equipment. The pupil distance self-adaptive observing equipment comprises a first eye lens and a second eye lens, wherein the distance between the principle optic axis of the first eye lens and the principle optic axis of the second eye lens is fixed and unchanged, and the first eye lens and the second eye lens are of a multi-level structure with different off-axis amounts. The distance between the principle optic axis of the first eye lens and the principle optic axis of the second eye lens is 62mm. The first eye lens and the second eye lens are of a trebling structure with the off-axis amounts of +4mm, 0mm and -4mm respectively, and the exit pupil diameter of each level structure is 6mm. The pupil distance does not need to be adjusted in the using process of the pupil distance self-adaptive observing equipment, and thus the pupil distance self-adaptive observing equipment has the advantages of being simple in structure and high in reliability.
Description
Technical field
The present invention relates to optical instrument technical field, especially a kind of interpupillary distance self-adaptation facilities for observation.
Background technology
Facilities for observation, as telescope, generally adopts the form of single tube binocular, double-pipe binocular, single tube monocular, but in order to meet the observation habit of human eye, facilities for observation majority is designed to binocular form.Due to the interpupillary distance difference of different crowd, the adjustable mode of interpupillary distance is taked in the design of most facilities for observations, as:
1) as shown in Figure 1, one group of eyepiece is fixed, another group eyepiece relative motion.This kind of form need to separate eyepiece mount and fix by pressing plate with Instrument shell, in addition O-ring seal ensures sealing.
2) as shown in Figure 2, two groups of eyepieces all can be movable relatively.This kind of form and the first form class seemingly, just by one group fix one group move transfer to two groups all removable, but reliability is poorer than the first, reason is will more resealing links;
3) as shown in Figure 3, centered by axle, pivoted arm is radius, by relatively rotating between the eyepiece component of two of left and right, realizes the adjusting of interpupillary distance.This kind of interpupillary distance regulates form to be most widely used in all kinds of white light telescopes, but number of parts is more and structural member is also comparatively complicated, and reliability is poor.
Therefore, above several interpupillary distance regulative modes all, by comparatively complicated rotation, the adjusting requirement that travel mechanism realizes interpupillary distance, make instrument number of components increase for this reason, and weight increases, and have reduced the reliability of instrument.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of interpupillary distance self-adaptation facilities for observation, this facilities for observation use process in without regulate interpupillary distance, therefore have simple in structure, the feature that reliability is high.
In order to solve the problems of the technologies described above, the present invention includes the first eyepiece and the second eyepiece, between described the first eyepiece and the primary optical axis of the second eyepiece, distance immobilizes, and described the first eyepiece and the second eyepiece are to have the different multiplets from axle amount.
Preferably, the distance between described the first eyepiece and the primary optical axis of the second eyepiece is 62mm.
Preferably, described the first eyepiece and the second eyepiece for from be respectively+4mm of axle amount, 0mm and-triplen of 4mm, every weight structure exit pupil diameter is 6mm.
Because eyepiece of the present invention is to have the different multiplets from axle amount, therefore can be suitable for the observer of different interpupillary distances, and without the distance regulating between the first eyepiece and the second eyepiece, can omit the mechanism of distance between facilities for observation adjusting eyepiece, make facilities for observation structure more simple, improved its reliability simultaneously.
Brief description of the drawings
Fig. 1, Fig. 2 and Fig. 3 are the interpupillary distance regulative mode schematic diagram of existing facilities for observation;
Fig. 4 is structure principle chart of the present invention.
Embodiment
The embodiment that the present invention is cited; just for helping to understand the present invention; should not be construed as limiting the scope of the present invention; for those skilled in the art; without departing from the inventive concept of the premise; can also the present invention be improved and be modified, these improvement and modification also fall in the scope of the claims in the present invention protection.
As shown in Figure 4, the present invention includes the first eyepiece 1 and the second eyepiece 2, between described the first eyepiece 1 and the primary optical axis of the second eyepiece 2, distance immobilizes, and because most people's interpupillary distance is all in 62mm left and right, between the first eyepiece 1 and the primary optical axis of the second eyepiece 2, preferred distance is 62mm.
The present invention, in the design of eyepiece, carries out observation point from axle optimal design, during by ZEMAX Software for Design eyepiece system, makes described the first eyepiece 1 and the second eyepiece 2 for having the different multiplets from axle amount.Preferably from be respectively+4mm of axle amount, 0mm and-triplen of 4mm, every weight structure exit pupil diameter is 6mm, the observing effect of the human eye of simulating different interpupillary distances on different eyespots 3, the picture element of the each weight structure eyepiece system of balance simultaneously, mainly comprise and affect the coma of imaging definition, astigmatism and chromatic longitudiinal aberration, make the human eye of different interpupillary distances can meet the requirement of resolving power by this eyepiece system observation image.Thereby make all groups of interpupillary distance scope 54mm～70mm can be suitable for the present invention.
The relative conventional view equipment of the present invention, has the following advantages:
1, equipment applicability is wide, and the present invention is applicable to all kinds of binocular optical equipment, as prismatic decomposition, reflection lens one-shot, the eyepiece system such as OLED eyepiece component independently, all can meet usability requirement through the present invention.
2, crowd's applicability is wide, and eyepiece of the present invention is applicable to the crowd of different interpupillary distances, through optimal design, can meet all groups of interpupillary distance scope 54mm～70mm.
3, use comfortablely, eyepiece system of the present invention, need not regulate interpupillary distance mechanism repeatedly, simple to operate; Owing to having used large exit pupil diameter, it is larger that different crowd moves left and right surplus in the time observing, and limitation is little, therefore uses comparatively comfortable.
4, mechanism is reliable, and eyepiece of the present invention mechanism does not exist the links such as adjusting, sealing, rotation, and amount of parts is few, simple in structure, good reliability.
