Abstract
The utility model provides a medical hard endoscope image rotating lens, which enables a HOPKINS rod lens to be combined with an erecting prism, and the image rotating lens becomes a mirror image after three reflections. The medical hard endoscope image rotating lens aims to solve the problem that an eye pupil does not overlap a system exit pupil after the erecting prism is additionally arranged in an eye lens system, so as to enable the eye pupil to overlap the system exit pupil. The medical hard endoscope image rotating lens is convenient to install and adjust, is applicable to the endoscope system with a Dove prism behind the eye lens, and can serve as the last image rotating lens for the image rotating system by taking the structural design into consideration.
Description
Technical field
The utility model relates to a kind of medical rigid endoscope image rotation lenses, belongs to the optical engineering applied technical field.
Background technology
The relay system majority of medical rigid endoscope is made up of HOPKINS rod lens at present.Because operation needs, medical rigid endoscope has different line of vision angle mirror bodies, make deflection of light with prism in its optical system, if it is odd number that the system front adds the reflecting surface number of prism, will produce mirror image, also will add erecting prism so after optical system, common this type system adds the power and influence mirror one behind eyepiece.Owing to add erecting prism behind the eyepiece, so just cause eye pupil not overlap with the system emergent pupil, form vignetting greatly.
Summary of the invention
In order to solve owing to adding the problem that erecting prism causes eye pupil and system emergent pupil not to overlap behind the eyepiece system, the utility model proposes a kind of medical rigid endoscope image rotation lenses, the excellent lens of HOPKINS are combined with erecting prism.
A kind of medical rigid endoscope image rotation lenses as shown in Figure 1, comprises first 1, second portion 2, third part 3 and the 4th part 4; Described first 1 is glued together with second portion 2; Second portion 2 is glued together with third part 3; Third part 3 and the 4th part 4 are glued together; Wherein 11 faces of first 1 are planes of light incidence, this face plating anti-reflection film; 22 faces of second portion 2 are light reflectings surface, this face plating reflectance coating; 23 and third part 3 gummeds of second portion 2; 31 faces of third part 3 are light reflectings surface, this face plating reflectance coating; 41 faces of the 4th part 4 are beam projecting faces, this face plating anti-reflection film.
Light is injected from 11 faces of first 1, and light beam is through 21 reflections of second portion 2,22 reflections of second portion 2, through 23 transmissions of second portion 2, passes through after 31 reflections of third part 3 41 ejaculations by the 4th part 4 then.Image rotation lenses becomes mirror image through triple reflection.
Beneficial effect
The utility model has solved owing to adding the problem that erecting prism causes eye pupil and system emergent pupil not to overlap behind the eyepiece system, make eye pupil overlap with the system emergent pupil, be convenient to debug, can be applicable to have into behind the eyepiece endoscopic system of prism, consider structural design, the medical rigid endoscope image rotation lenses of this kind can be used as last image rotation lenses of relay system.
Description of drawings
Fig. 1 is the utility model structure principle chart.This figure also is the specification digest accompanying drawing.Wherein: 1 is first, and 2 is second portion, and 3 is third part, and 4 is the 4th part.
Fig. 2 is background technology HOPKINS rod lens synoptic diagram.Wherein: 5 is HOPKINS rod lens left ends, and 6 is HOPKINS rod lens right-hand members.
Embodiment
As shown in Figure 1, a kind of medical rigid endoscope image rotation lenses comprises first 1, second portion 2, third part 3 and the 4th part 4.Described first 1 is glued together with second portion 2; Second portion 2 is glued together with third part 3; Third part 3 and the 4th part 4 are glued together; Wherein 11 faces of first 1 are planes of light incidence, this face plating anti-reflection film; 22 faces of second portion 2 are light reflectings surface, this face plating reflectance coating; 23 and third part 3 gummeds of second portion 2; 31 faces of third part 3 are light reflectings surface, this face plating reflectance coating; 41 faces of the 4th part 4 are beam projecting faces, this face plating anti-reflection film.
Light is injected from 11 faces of first 1, and light beam is through 21 reflections of second portion 2,22 reflections of second portion 2, through 23 transmissions of second portion 2, then after 31 reflections of third part 3 by 41 ejaculations of the 4th part 4.First 1 is identical with HOPKINS rod lens left end 5 among Fig. 2, and the 4th part 4 is identical with HOPKINS rod lens right-hand member 6 among Fig. 2; Second portion 2 and third part 3 are two prisms of gummed.
This medical rigid endoscope image rotation lenses can be applicable to have behind the eyepiece endoscopic system of Dove prism, considers structural design, and the medical rigid endoscope image rotation lenses of this kind can be used as last image rotation lenses of relay system.
