Abstract
The invention discloses an endoscope with an optical isolation device. The endoscope comprises an annular plane lens, a circular lens, an imaging optical lens group and an object lens seat, wherein the circular lens is embedded in the annular plane lens, an annular isolation surface is formed between the circular lens and the annular plane lens, LED light sources are uniformly distributed on an inner surface of the annular plane lens, the object lens seat is closely attached to the circular lens, and the imaging optical lens group is arranged in the object lens seat. The endoscope with the optical isolation device is capable of optically isolating a light transmission area from an image guiding area on plane glass, and avoiding useless light rays from interfering images.
Description
Technical field
The present invention relates to a kind of endoscope, relate in particular to a kind of endoscope with light image spacer assembly.
Background technology
The general optical fiber that uses of conventional endoscope illumination has two optical fiber output points in the endoscope termination, and output terminal increases by two leaded light windows and lens again, optical fiber is gathered the position that needs illumination.Along with the raising of endoscope miniaturization requirement and the development of LED lighting engineering; The increasing endoscope selection use LED of enterprise annular light source still for the needs of waterproof sealing, must increase a flat glass at camera lens and source ends; But flat glass has two faces; In through light, also can the light of illumination be reflected, when the light of reflection just arrives imaging region, will influence the quality of imaging.Though can pass light and lead the picture zone with making through the thickness that reduces eyeglass as far as possible away from reducing effect; For example number of patent application is 02155996.1 application for a patent for invention " endoscope optical system with the window that hides ray conductor and image conductor "; This application has adopted O shape circle to isolate, and makes light as far as possible away from the method for leading the picture district.But no matter what reduce, two faces of eyeglass exist all the time, so the influence of picture quality is also existed all the time.The intensity that reduces to reduce protection of thickness causes the flat slide of end face to damage easily in addition, reduces the ability of water, vapour protection.
Summary of the invention
The technical matters that the present invention will solve is; Pass through the above-mentioned defectives such as interference of flat glass to endoscope head end illuminating ray in the prior art to image quality; A kind of specific combination eyeglass is provided; To pass the light zone and on flat glass, carry out isolation, and make illuminating ray can't get into camera, stop of the interference of useless light image with leading as the zone.
The technical solution adopted for the present invention to solve the technical problems is: a kind of endoscope with light image spacer assembly comprises planar annular eyeglass, circular eyeglass, image optics lens set and objective holder; Circular eyeglass is embedded in the planar annular eyeglass, forms the annular isolation face between the two; Planar annular eyeglass inboard is evenly distributed with led light source, and objective holder and circular eyeglass are close to, and the image optics lens set places in the objective holder.
In endoscope of the present invention, also comprise the camera target surface that is positioned at the objective holder rear.Aforementioned camera target surface mainly is responsible for converting target image to vision signal, is resent to driving and Flame Image Process, the display system of the endoscope of establishing in addition.
In endoscope of the present invention, the external diameter of objective holder equates with the external diameter of circular eyeglass.
The principle of work of endoscope according to the invention is: target is through circular eyeglass; Through the image optics lens set, image in the camera target surface, the light that led light source sends is through the output of planar annular eyeglass; Target is thrown light on; Because the annular isolation face is arranged, the reflection that the light that led light source sends can not pass through the planar annular eyeglass gets into circular eyeglass, thereby has avoided the interference of illumination light secondary reflection light to image.
In endoscope of the present invention; Circular eyeglass is embedded in the planar annular eyeglass; With the surface of contact of circular eyeglass and planar annular eyeglass hacking limit all; And then coat black glue, so just with being processed into the annular isolation face that light is isolated between planar annular eyeglass and the circular eyeglass, used in the present invention black glue can be known various black glue.
In endoscope of the present invention, the image optics lens set belongs to known technology in the art, can adopt the image optics lens set of being made up of two convex lens in the present invention.
In endoscope of the present invention; Because the planar annular eyeglass is an annular; Also possessed the advantage that is similar to the LED annular light source so be evenly distributed on the inboard led light source of planar annular eyeglass; Promptly do not have stroboscopic, even, the no diplopia generation of illumination and sharpness high, so just can guarantee that led light source itself can not produce interference to image.
Advantage of the present invention has provided a kind of endoscope with light image spacer assembly, and this endoscope has passing the light zone and leading the picture zone and on flat glass, carry out isolation, stop the advantages such as interference of useless light to image

Existing that label declaration in the accompanying drawing is following: 1 is the planar annular eyeglass, and 2 is circular eyeglass, and 3 is led light source, and 4 is the image optics lens set, and 5 is the camera target surface, and 6 is objective holder, and 7 is the annular isolation face, and 8 is flat glass.
Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
In preferred embodiment of the present invention, as depicted in figs. 1 and 2, said endoscope comprises planar annular eyeglass 1, circular eyeglass 2, led light source 3, image optics lens set 4, camera target surface 5 and objective holder 6; Wherein, Circular eyeglass 2 is embedded in the planar annular eyeglass 1, forms 7,4 led light sources 3 of annular isolation face between circular eyeglass 2 and the planar annular eyeglass 1 and is evenly distributed on planar annular eyeglass 1 inboard; The external diameter of objective holder 6 equates with the external diameter of circular eyeglass 2; And objective holder 6 is close to circular eyeglass 1, is built-in with image optics lens set 4 in the objective holder 6, and camera target surface 5 is at objective holder 6 rears; Main being responsible for converts target image to vision signal, is resent to driving and Flame Image Process, the display system of the endoscope of establishing in addition.
As shown in Figure 3, form annular isolation face 7 through operations such as hacking and blacking glue between planar annular eyeglass 1 and the circular eyeglass 2, image optics lens set 4 grades of endoscope inside are protected.Target is through circular eyeglass 2; Image optics lens set 4 through in the objective holder 6 images in camera target surface 5, and the light that led light source 3 sends is through 1 output of planar annular eyeglass; Thereby target is thrown light on; Because the existence of annular isolation face 7 is arranged, the light that led light source 3 sends gets into circular eyeglass 2 with regard to not passing through the reflection of planar annular eyeglass 1, thereby has avoided the interference of illumination light reflection to image.
Should be understood that, concerning those of ordinary skills, can improve or conversion according to above-mentioned explanation, and all these improvement or conversion all should belong to the protection domain of accompanying claims of the present invention.
