Supplementary Figure S1 Optical images of a semi-immersed microscale lens on a
large object.
The lens is semi-immersed in the index-matching oil, and the distance d between the
lens and the object is about 3.1 μm. A virtual image (1.38×, s1-1) and a real image
(-1.80×, s1-2) are formed. The large object is fabricated with the 960 nm
microspheres. The results are similar to the case when the lens is semi-immersed in
the SU-8 resist. The scale bar is 2 μm.
Supplementary Figure S2 Optical images of a semi-immersed microscale lens on a
random object.
The lens is semi-immersed in the SU-8 resist, and the object is fabricated with the 960
nm microspheres which are randomly packed.
The distance d between the lens and the object is about 3.1 μm. A virtual image
(1.50×, s2-1) and a real image (-1.85×, s2-2) are formed. The results are similar to the
case when the microspheres are hexagonally close-packed. The scale bar is 2 μm.
