The 2D cross-sectional view with the that the 2D microstructures was film microstructure includes a It can be seen within the figure curved film surface profile of theexamined by optical microcircular arc shape using a height of about 60 m. The fabricated film microstructure IL-4 Protein Technical Information arrays might be employed as optical elements. A projection experiment was performed to illustrate the utility of those microstructures as microlens array for optical display application (Figure 4a). The film microstructure array was positioned on the sample stage of an optical microscope, in addition to a printed transparency(a)Micromachines 2021, 12,four ofscope (Nikon SMZ1270, colored film microstructures, Nikon, Tokyo, Japan). The 2D surface profile of a standard curved microstructure was characterized by profiler (VeecoDektak 150, Veeco, Plainview, NY, USA). three. Final results and Discussion Figure 3a,b display the 2D morphology on the fabricated film microstructure array. The 2D profiles seem incredibly uniform, showing a circular shape with a diameter of around 250 , which can be almost equal to the diameter of the holes in the PDMS sheet. The 3D surface topography with the film microstructures is presented in Figure 3c, plus the 2D cross-sectional view in the film microstructures is presented in Figure 3d. Besides excellent uniformity, the smooth connection together with the flat film in the bottom from the microstructures is observed from the figures. The 2D surface profile of a standard curved film microstructure is displayed in Figure 3e, which also shows the fitted circle that has a radius of 128.4 .
