Description
Technical field
This utility model relates to a kind of ophthalmic optical-instruments, particularly a kind of mobile phone inspection eye preset lens.
Background technology
Eyes are major organs that human body accepts external information, and optical fundus is then the important component part of eyes.Extraneous things, by the prosthomere (dioptric system) of eyes, is imaged on deutomerite (optical fundus), is then delivered to brain by optic nerve and produces vision.Human eye (as retina) pathological manifestations not only disease with eyes own is relevant, and also have certain association with health some other diseases (as diabetes), the patient of diabetes, often there is retinopathy in early days, then it is analyzed by taking a picture to eye ground, can find eyes and some other diseases of health early, very large first chance has been won in the treatment for disease.
Ophthalmoscope, also known as ophthalmofundoscope, is usually used in the inspection of people's ophthalmic, as cornea, and tear, whether the transparent medium such as crystalline lens and vitreous body is abnormal; Retina, choroid, the pathological changes situation of papilla of optic nerve, retinal vessel etc.Tradition ophthalmoscope is visual type, and doctor observes patient's eye with eyes through ophthalmoscope.Use ophthalmoscope to carry out examination of ocular fundus and need to be grasped certain technology, the equipment of specialty and the operant skill of equipment, be difficult to popularize.
Along with the development of technology, the arrival of information age, mobile phone is very universal, function also gets more and more, especially smart mobile phone, not only has camera function, and can also show the image of subject, photography, stores, process and transmission, these functions are all very useful for eye examination, carry out examination of ocular fundus provide possibility for utilizing smart mobile phone.
Summary of the invention
The purpose of this utility model there are provided a kind of with mobile phone with the use of, make mobile phone have the mobile phone inspection eye preset lens of examination of ocular fundus function.
To achieve these goals, the utility model discloses a kind of mobile phone inspection eye preset lens, comprise shooting light path and illumination path, it is characterized in that: described mobile phone inspection eye preset lens comprises dioptric element, described dioptric element is plane mirror or reflecting prism, mobile phone light source is refracted to tested eye optical fundus and forms described illumination path by described dioptric element, described dioptric element comprises illuminating ray the most at last and reflexes to the main dioptric element on tested eye optical fundus and one or more are for reflecting the secondary dioptric element turned to by illuminating ray, also condenser lens is provided with in described illumination path.
Preset lens of the present utility model is owing to being provided with described dioptric element and beam splitter, mobile phone light source is refracted to the illumination path on tested eye optical fundus, match with the camera position on mobile phone and light path of making a video recording, therefore mobile phone can utilize the light source self be furnished with to throw light on to optical fundus, mobile phone is made to have possessed condition to fundus angiography or photography, for masses provide a kind of easy-to-use, economical, are easy to universal examination of ocular fundus device.
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Accompanying drawing 1 is this utility model specific embodiment 1 light path system schematic diagram;
Accompanying drawing 2 is this utility model specific embodiment 2 light path system schematic diagram.
Detailed description of the invention
This mobile phone inspection eye preset lens comprises dioptric element, described dioptric element is plane mirror or reflecting prism, mobile phone light source is refracted to tested eye 5 optical fundus and forms illumination path by described dioptric element, described dioptric element comprises illuminating ray the most at last and reflexes to the main dioptric element 6 on tested eye 5 optical fundus and one or more are for reflecting the secondary dioptric element 3 turned to by illuminating ray, is also provided with condenser lens in described illumination path.Mobile phone light source reflects by described dioptric element, match with the camera position on mobile phone 1 and light path of making a video recording (i.e. mobile phone 1 photographic head central axis), namely want and on mobile phone 1 mutual alignment between photographic head 7 and light source 2 suitable, mobile phone 1 light source 2 is refracted to tested eye 5 optical fundus.To illustrate further below:
Specific embodiment 1
As shown in Figure 1, mobile phone inspection eye preset lens comprises dioptric element, described dioptric element comprises main dioptric element 6 and one or more are for reflecting the secondary dioptric element 3 turned to by illuminating ray, the quantity of secondary dioptric element 3 is determined according to the concrete line alignment of illuminating ray, main dioptric element 6 and a secondary dioptric element 3 is provided with in this specific embodiment, described main dioptric element 6 is arranged in shooting optical axis, described main dioptric element 6 is made up of plane beam splitter or Amici prism, eye preset lens compact overall structure is examined in order to make mobile phone, described main dioptric element 6 reflecting surface preferably with shooting optical axis be that 45 ° of angles are arranged, described dioptric element is plane mirror or reflecting prism, reflecting surface and described main dioptric element 6 reflecting surface of described dioptric element be arranged in parallel, the center of described secondary dioptric element 3 is identical with the distance in the distance between shooting optical axis and mobile phone 1 between photographic head 7 and light source 2, like this, the light that light source 2 sends successively overlaps with shooting light path after dioptric element and main dioptric element 6 reflect, and throws light on to optical fundus.In order to improve the convergence of light, reduce optical energy loss, be also provided with condenser lens 4 in described illumination path, described condenser lens 4 can be arranged on the optional position in illumination path, in this specific embodiment, described condenser lens 4 is arranged between main dioptric element 6 and secondary dioptric element 3.
