Embodiment 1
[0030] Such as Figure 1a As shown, this embodiment includes: a compound eye base and a circular structure fly eye lens, wherein: the compound eye base has a spherical crown base with a diameter of 1 cm and a height of 4 mm, and the fly eye lens is a spherical convex lens with a diameter of 160 microns and a height of 16 microns.
[0031] The present embodiment is prepared through the following steps:
[0032] The first step is to clean the silicon wafer substrate, sputter chromium on the silicon wafer substrate, and make a metal layer with a thickness of 100 angstroms;
[0033] Such as Figure 1b As shown, the second step is to spin-coat photoresist on the surface of the metal layer, and then use a circular compound eye array structure to form a columnar convex structure through photolithography;
[0034] The circular compound eye array has a cylindrical diameter of 150 microns and a height of 18 microns.
[0035] The third step is to place the photoresist-coated silicon wa...

[0051] The present embodiment is prepared through the following steps:
[0052] The first step is to clean the silicon wafer substrate, sputter chromium on the silicon wafer substrate, and make a metal layer with a thickness of 100 angstroms;
[0053] The second step is to spin-coat photoresist on the surface of the metal layer, and then use a mask plate with a hexagonal column array structure to form a columnar convex structure through photolithography;
[0054] The hexagonal pillars have a diameter of 180 microns and a height of 21 microns.
[0055] The third step is to place the photoresist-coated silicon wafer substrate i...
Embodiment 3
[0070] Such as Figure 3a-Figure 3d As shown, this embodiment includes: a compound eye base and a fly eye lens with a square structure, wherein: the diameter of the compound eye base is a hollow spherical base with a height of 2 cm and a height of 8 mm, the hollow diameter of which is 1 cm and a height of 3 mm, and the fly eye lens has a side length of 180 Micron, a square convex lens with a height of 20 microns.
[0071] The present embodiment is prepared through the following steps:
[0072] The first step is to clean the silicon wafer substrate, sputter chromium on the silicon wafer substrate, and make a metal layer with a thickness of 100 angstroms;
[0073] The second step is to spin-coat photoresist on the surface of the metal layer, and then use a mask plate with a square compound eye array structure to form a columnar convex structure through photolithography;
[0074] The square columns of the square compound eye array have a diameter of 175 microns and a height of ...
