(a) Complete compound eyes; (b) SEM image of the details of ommatidia. The inset figure is magnified SEM image to show the sub-wavelength structure array in one ommatidium (The scale bar inset is 1 μm.); (c) Schematics of refractive index variations experienced by incident light: (i) flat UV-curable resin coating, (ii) columnar sub-wavelength structure, (iii) triangular sub-wavelength structure, and (iv) conical sub-wavelength structure; (d) Infrared spectrum analysis of the UV-curable resin GP756.
