Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be understood by those skilled in the art.That addresses in the present invention is forward and backwardly according to the usual observation visual angle of those skilled in the art and describes convenient and definition, do not limit concrete direction, to be in use front near the side of observed person's eyeball and after the side (eyepiece 10) of observer is, as specifically corresponded to downside and the upside of paper in Fig. 2.
Fig. 1 and the operation microscope that Figure 2 shows that a kind of observable optical fundus of the present invention.Shown in composition graphs 1, Fig. 2, microscope has optical system, and optical system is made up of illumination optical system and image acquisition light path system, is respectively used to throw light on to optical fundus and gather eye fundus image.Optical system comprises light source 1, collecting lens group 2, projection lens group 3, reflecting mirror 4, attachment objective 5, inversion prism 6, non-spherical lens 7, zoom objective group 8, turns to prism 9 and eyepiece 10.Wherein, reflecting mirror 4, collecting lens group 2, projection lens group 3 and reflecting mirror 4 form illumination optical system, and attachment objective 5, inversion prism 6, non-spherical lens 7 are arranged in the projecting light path of illumination optical system successively; Non-spherical lens 7, inversion prism 6, attachment objective 5, zoom objective group 8, prism 9 and eyepiece 10 is turned to set gradually and composing images gathers light path system from A-P.
Illumination optical system adopts Kohler illumination design, light source 1 adopts the visible LED with high color rendering index (CRI), can by the visible light beam of LED institute outgoing through the aperture diaphragm place imaging of collecting lens in projection lens group 3, be projected on reflecting mirror 4 through projection lens group 3 again, attachment objective 5 is reflexed to by reflecting mirror 4, be projected to optical fundus via inversion prism 6, non-spherical lens 7 successively again, realize the Uniform Illumination in fundus observation face.Eye ground, through eyeball, non-spherical lens 7 refractive power, then through guiding prism inverted image, then through attachment objective 5, zoom objective group 8, by turning on the focal plane of prism 9 imaging eyepiece 10 again, entering through eyepiece 10 and observing eyes.Attachment objective 5 and Zoom lens group composing images gather the object lens of light path system, and wherein, attachment objective 5 is used for increasing visual field, operating distance can be increased, can provide larger operation technique space accordingly; Zoom objective group 8 is electrodeless zoom objective group 8, multiple continuous variable.
Tool of the present invention has the following advantages:
Light source 1 adopts the visible LED of long-life, high color rendering index (CRI), and the Halogen light used with conventional microscope in prior art is compared, and has higher definition and color reducibility, and has longer service time;
The wave-length coverage of the light beam of light source 1 outgoing is visible spectrum, and the Halogen light used with conventional microscope in prior art is compared, and can not produce ultraviolet light, infrared light injury, can not bring out cataract and other fundus oculi diseases to eyes;
Illumination path adopts Kohler illumination, realizes the Uniform Illumination of sightingpiston, makes observation more clear;
Image acquisition light path system adopts guiding prism to carry out inverted image, and make optical fundus become forward through the crystalline lens of eyeball with the inverted image of non-spherical lens 7 one-tenth, what last observer was seen similarly is positive, is beneficial to operation Shi doctor operation;
Image acquisition light path system adopts non-spherical lens 7, and non-spherical lens 7 pairs of aberrations have good correcting, make fundus observation more clear, and non-spherical lens 7 is comparatively near apart from patient's eye simultaneously, and contributing to the observation visual field increasing optical fundus, is that the visual field is larger;
Inversion prism 6 and non-spherical lens 7 are positioned at the front portion of image acquisition light path, closer to eyeball, simplify the setting of image acquisition light path system, such that microscope overall structure is simple, small volume, cost are lower.
Above-described embodiment for technical conceive of the present invention and feature are described, is only a kind of preferred embodiment, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.The equivalence change that all spirit according to the present invention are done or modification, all should be encompassed within protection scope of the present invention.
