[0023] An eye surface texture capture device, such as Figure 1-Figure 8 As shown, it includes a cylindrical collection body 1, a built-in light source 2, a light-shielding ring 3, a back cover 4, a high-resolution macro lens 5 and a CPL filter 7. The cylindrical collection body 1 is threadedly connected to the back cover 4. The light-shielding ring 3 is arranged on the upper base 42 of the back cover 4. The built-in light source 2 is arranged on the bottom groove 32 of the light-shielding ring 3. A first light line gap 11 for a power connection channel of the built-in light source 2 is arranged on the cylindrical collection body 1. A second light line gap 31 for a power connection channel of the built-in light source 2 is arranged on the light-shielding ring 3. A third light line gap 41 for a power connection channel of the built-in light source 2 is arranged on the back cover 4. The first light line gap 11, the second light line gap 31 and the third light line gap 41 are in a straight line. A lower base 71 of the CPL filter 7 is arranged on the upper base 42 of the back cover 4. The CPL filter 7 passes through the back cover 4. The high-resolution macro lens 5 is sleeved on the CPL filter 7 and threadedly connected to the back cover 4. A fixing device for fixing to the camera is arranged on the high-resolution macro lens 5.

[0024] The fixing device is threadedly connected to the high-resolution macro lens 5 .

[0025] The fixing device is a mobile phone clamp 6, and a camera through hole 61 is provided on the mobile phone clamp 6 for exposing the camera field of view.

[0026] Wherein, the built-in light source 2 is a light strip.

[0027] Wherein, a switch 21 and a USB port 22 are arranged on the external power connection line of the light strip.

[0028] Wherein, a movable limiting rubber ring 43 is sleeved on the threaded outer wall of the rear cover 4 .

[0029] The utility model involves the following five devices

[0030] (1) Cylinder collection body

[0031] This part is designed based on the optimal imaging distance and performance of the macro lens. The main part includes a cylindrical main structure with an opening at the front end for aligning the eye. This part is designed with threads and light wire notches to connect with the light shield and the back cover. The threaded connection ensures that each part is stable and easy to disassemble and replace, while the light wire notches provide the necessary power connection channel for the built-in light source to ensure that the light source can work stably.

[0032] (2) Built-in light source

[0033] The yellow light strip is wrapped around and fixed to the light shield, providing uniform illumination. The light strip is powered by its own USB port and switch, which can dim the light source, ensuring that the device can work without external wiring. The design of the light strip ensures eye clarity in closed environments.

[0034] (3) Light-avoiding circle

[0035] The main function of the light shield is to prevent the light from the built-in light source, such as the light strip or light ring, from spilling out, so as not to interfere with the image quality and resolution. The light shield is also the carrier of the light source. After many tests and precise calculations, the diameter of the light strip on the light shield and the distance from it to the eye can just make the light focus on the pupil to avoid interference with the eye surface texture. This design can minimize light reflection and scattering, and improve image clarity and contrast.

[0036] (4) Back cover

[0037] The back cover is designed with raised threads and a base to connect the macro lens to the camera. The raised threads ensure that the back cover can be firmly fixed to the camera, while the base provides a stable support structure for the macro lens to prevent the lens from shifting during use.

[0038] (5) High-resolution macro lens

[0039] The device has a high-resolution macro lens with a focal length range of 30mm-120mm and a CPL filter installed on the back. The lens is designed to improve the performance of mobile device cameras and can capture high-quality images of eye details. The CPL filter is used to reduce reflected light and glare, and improve image contrast and clarity. The macro lens uses high-quality optical materials and precision design to provide excellent resolution at close distances. Its standard thread interface and fixing clip make it easy to install the lens on a mobile phone or tablet, which is simple and quick to operate without the need for additional tools.

[0040] The working process of the utility model equipment

[0041] The present invention relates to an iris and outer eye texture shooting peripheral, which is specially designed for the camera of mobile phones, tablets or other mobile devices. The device can be installed and operated through simple steps without additional software or configuration, and is particularly suitable for medical diagnosis, sub-health monitoring and large-scale low-cost data set collection.

[0046] 3. The user starts the camera application on the mobile phone or tablet.

[0047] 4. After installing this peripheral, the user can achieve the best clarity by adjusting the brightness of the peripheral's auxiliary light source and the focus of the mobile device's lens.

[0048] 5. The user focuses on the eyes to capture the image.

[0049] Image evaluation and use

[0050] 6. The captured image will be displayed on the screen of the mobile phone or tablet, and the user can directly view and evaluate the image quality.

[0051] 7. If necessary, users can use any standard or professional image processing software on their mobile phone or tablet for further image analysis.

[0052] Preparation for disassembly and storage

[0053] 8. After use, users can easily disassemble the peripherals. The device is small and portable, with modular design, easy to store and carry, suitable for various occasions.
