Abstract
The invention discloses an eye-distance-adjusting-free optical structure of a binocular observation ocular lens. The optical structure comprises an ocular lens and a combined prism. The combined prism consists of a light splitter, a left prism, and a right prism; the light splitter is an isosceles rectangular prism, the inclined surface of the light splitter is located on a light path of light beam incidence, and two right-angle surfaces of the light splitter are light splitting surfaces; the left prism and the right prism are right-angle trapezoid prisms; the right angle surfaces, opposite to slant edge surfaces, of the left prism and the right prism are in contact with the right-angle surface of the light splitter; and slant edge surfaces of the left prism and the right prism are located on a light beam outgoing path. According to the eye-distance-adjusting-free optical structure provided by the invention, eye distance adjustment is not required; and the structure is simple and the operation becomes convenient.
Description
Technical field
The invention belongs toInImaging and observational technique field, the two order relating in particular to a kind of adjustment-free eye-distance observes the optics structure of eyepiece.
Background technology
The low-light binocular paired eyepiece of prior art adopts collimated, prismatic decomposition, middle object lens optically focused, the form that prism turns to, eyepiece is observed, complex structure, adjustment difficulty. Operating, different viewers needs to adjust according to my eye-distance, cumbersome.
Summary of the invention
It is an object of the invention to the defect for above-mentioned prior art, it is provided that two order of a kind of adjustment-free eye-distance observes the optics structure of eyepiece, need not regulate eye-distance. Structure is simple, easy to operate.
In order to realize above-mentioned purpose, the technical scheme of the present invention is:
Two order of adjustment-free eye-distance observes an optics structure for eyepiece, comprises eyepiece and component prism; Described component prism comprises spectroscope and left prism, right prism, and described spectroscope is isosceles right-angle prism, and described spectroscopical inclined-plane is in the light path of light beam incidence, and described spectroscopical two right-angle surface are light splitting surface; Described left prism, right prism are right-angled trapezium prism, and the right-angle surface relative with oblique faceted pebble of described left prism, right prism fits with spectroscopical right-angle surface respectively, and the oblique faceted pebble of described left prism, right prism is in the outgoing light path of light beam. Described spectroscope is in eyepiece light and injects in light path, described left and right prism is on direction, spectroscopical left and right, eyepiece collimated light beam through spectroscope by entering left and right prism after 1:1 light splitting, after left and right prism folding, reflection, it is possible to ensure image planes brightness that eyes observe evenly, close as clear.
As the improvement to technique scheme, the distance of described left prism, right prism outgoing beam is 63mm.
As the improvement to technique scheme, described eyepiece is heavy caliber, and long eyespot is apart from eyepiece, and the effective pore radius of described eyepiece is footpath 15mm.
The light that image planes send, turns into collimated light beam after eyepiece, and spectroscope is a prism square, incident from inclined-plane, in two right-angle surface, light splitting occurs, and the light beam separated, after left and right prismatic refraction and reflection, arrives eyespot position. When designing eyepiece, can seeing whole visual field in the relative broad range of eyespot position, two eyespot position optical axises, at a distance of 63mm, can both see full filed within the scope of the diameter 15mm of eyespot position, night, when people's eye pupil diameter is 6mm, also can ensure the observation in eye-distance 54mm ~ 72mm.
Compared with prior art, have acquired by the present invention improve and useful effect be:
Two order of the adjustment-free eye-distance of the present invention observes the optics structure of eyepiece, the light that image planes send, turning into collimated light beam after eyepiece, spectroscope is a prism square, incident from inclined-plane, there is light splitting in two right-angle surface, component prism is made up of spectroscope and left and right prism cementing, and eyepiece collimated light beam is through spectroscope by entering left and right prism after 1:1 light splitting, and the light beam separated is after left and right prismatic refraction and reflection, arrive eyespot position, it is possible to ensure that the image planes brightness that eyes are observed is even, close as clear. Eyepiece is heavy caliber, long eyespot is apart from eyepiece, whole visual field can be seen in the relative broad range of eyespot position, two eyespot position optical axises are at a distance of 63mm, full filed can both be seen within the scope of the diameter 15mm of eyespot position, night, when people's eye pupil diameter is 6mm, also can ensure the observation in eye-distance 54mm ~ 72mm. This optics structure need not regulate eye-distance, and structure is simple, easy to operate.
Accompanying drawing explanation
Fig. 1 is the optics structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the technology of the present invention is described in further detail.
As shown in Figure 1, two order of the adjustment-free eye-distance of the present invention observes the optics structure of eyepiece, comprises eyepiece 1 and component prism; Described component prism comprises spectroscope 2 and left prism 3, right prism 4, and described spectroscope 2 is isosceles right-angle prism, and the inclined-plane of described spectroscope 2 is in the light path of light beam incidence, and two right-angle surface of described spectroscope 2 are light splitting surface; Described left prism 3, right prism 4 are right-angled trapezium prism, the right-angle surface relative with oblique faceted pebble of described left prism 3, right prism 4 respectively right-angle surface with spectroscope 2 fit, the oblique faceted pebble of described left prism 3, right prism 4 is in the outgoing light path of light beam. Described spectroscope 2 is in eyepiece light and injects in light path, described left prism 3, right prism 4 are on the direction, left and right of spectroscope 2, eyepiece 1 collimated light beam through spectroscope 2 by entering left prism 3, right prism 4 after 1:1 light splitting, after left prism 3, right prism 4 folding, reflection, it is possible to ensure that the image planes brightness that eyes are observed is even, close as clear.
The distance of described left prism 3, right prism 4 outgoing beam is 63mm.
Described eyepiece 1 is heavy caliber, and long eyespot is apart from eyepiece, and the effective pore radius of described eyepiece 1 is footpath 15mm.
The light that image planes 5 send, turns into collimated light beam after eyepiece 1, and spectroscope 2 is a prism square, incident from inclined-plane, in two right-angle surface, light splitting occurs, and the light beam separated arrives eyespot 6 position after reflecting through left prism 3, right prism 4 and reflecting. When designing eyepiece 1, can seeing whole visual field in the relative broad range of eyespot 6 position, two eyespot 6 position optical axises, at a distance of 63mm, can both see full filed within the scope of the diameter 15mm of eyespot 6 position, night, when people's eye pupil diameter is 6mm, also can ensure the observation in eye-distance 54mm ~ 72mm.
