Specific implementation mode
The utility model specific embodiment is described in detail below in conjunction with specific attached drawing.It should be noted that following implementations
Example described in technical characteristic or technical characteristic combination be not construed as it is isolated, they can be combined with each other from
And reach superior technique effect.In the attached drawing of following embodiments, the identical label that each attached drawing occurs represents identical spy
Sign or component, can be applied in different embodiments.
As shown in Figure 1, a kind of fundus imaging device based on mobile device of the utility model embodiment, including shell 10,
Light path of light component and image-forming assembly；
The light path of light component includes diaphragm 1, the third lens 2, the speculum 3, first being arranged in order along input path
Polaroid 4（Light splitting piece 8, the 4th lens 9 also belong to a part for light path of light）；The light path of light component is direct or indirect
It is fixed on the shell 10；
The image-forming assembly includes the second polaroid 5 being arranged in order, the first lens 6, the second lens 7, light splitting piece 8,
Four lens 9；The image-forming assembly is directly or indirectly fixed on the shell 10；
The speculum 3 is set to the side of the light splitting piece 8, and the reflecting surface of the speculum 3 and the light splitting piece 8 are right
