Abstract
The present invention relates to a door spyhole lens peeping lens, belonging to the field of optical design technology of reconnaissane tool. It is characterized by that it is formed from one mechanical entrance pupil, three groups of lens, one field lens and one mechanical emergent pupil. After entrance pupil is there first group of objective lens with large field of view, first group of large field objective lens and second group of projection objective lens with reduced mutiplying power are formed into totally positive image optical system by means of field lens. The human eye can oserve through third group of eye lens at emergent pupil place. Said product is butt-jointed with door spyhole lens from outdoor side, the indoor person and articles can be seen clearly.
Description
Technical field
The present invention is a kind of door eyehole lens, belongs to the manufacturing technology field of state security department with reconnaissane tool, particularly door eyehole lens optical design technical field.
Background technology
As everyone knows, from safety, peephole is housed all on the antitheft door of most of resident families, purpose is to see guest's situation outdoors clearly by peephole, whether to determine to open the door safety, can satisfy resident's request for utilization.Because the design feature that original big visual field of peephole and emergent pupil are positioned at camera lens inside, the people can't see indoor people and thing clearly by peephole outdoors, therefore, can't satisfy state security department and wish from outdoors to the indoor job requirement of scouting and monitoring.
Summary of the invention
The objective of the invention is to avoid above-mentioned the deficiencies in the prior art and a kind of door eyehole lens is provided.Adopt new optical design, people is outdoors docked " door eyehole lens " on peephole just can see indoor people and thing clearly, for state security department increases new reconnaissane tool.
Purpose of the present invention can reach by following measure: be made of a mechanical entrance pupil, three set of shots, a field lens and a mechanical emergent pupil: after the entrance pupil is first group of big visual field object lens, the projection objective of first group of big visual field object lens and second group of reduction magnification is combined into the optical system of totally positive image by field lens, and the 3rd group at emergent pupil place eyepiece of human eye observed.
Purpose of the present invention can also reach by following measure: first group of big visual field object lens are constituted by gummed mirror and concavees lens of gummed mirror, convex lens, concavees lens and the convex lens of concavees lens and convex lens; Field lens is convex lens; Second group of reduction magnification projection objective constituted by the gummed mirror and the convex lens of gummed mirror, concavees lens and the convex lens of convex lens, convex lens and convex lens; The 3rd group of eyepiece constituted by the gummed mirror of convex lens, convex lens and concavees lens.
The present invention compares prior art and has following advantage:
Adopt new optical design, people is outdoors docked " door eyehole lens " on peephole just can see indoor people and thing clearly, for state security department increases new reconnaissane tool; Aborning according to different technical characteristics, dissimilar peephole, design different parameters (such as: difference is gone into interpupillary distance, different field angle, different enlargement ratios etc.), the door eyehole lens of different model.
Embodiment
Description of drawings: accompanying drawing is an optical system configuration composition of the present invention.
The present invention will be described further in conjunction with the accompanying drawings: door eyehole lens is made of a mechanical entrance pupil, three set of shots, a field lens and a mechanical emergent pupil: after the entrance pupil 1 is first group of big visual field object lens 2, the projection objective 4 of first group of big visual field object lens 2 and second group of reduction magnification is combined into the optical system of totally positive image by field lens 3, and the 3rd group at emergent pupil 6 places eyepiece of human eye 5 observed.People outdoors is with door " mirror sight glass " when docking with peephole, first group of big visual field object lens 2 just can be imaged on indoor scene on the field lens 3, the projection objective 4 of second group of reduction magnification is imaged on first group of big visual field object lens 2 imaging on the image planes of the 3rd group of eyepiece 5 again, image planes are between convex lens 14,16, and human eye just can be observed indoor people and thing at emergent pupil 6 places by eyepiece 5.
