Figure 2. Design and characterization of imaging lenses used on 3D printed optical microscope.

Figure 2.

a) Imaging characteristic of the aspherical lens optimized under 532 nm illumination in Zemax. Scale bar: 1 mm. b) Simulated point spread function (PSF) for the optimized aspherical lens. c) to e): Tilted view of c) 3D printed aspherical lens, d) plastic aspherical lens from Edmund Optics (15–271) and e) molded acrylic aspherical lens from Thorlabs, Inc. (APL0303) respectively. Scale bars: 500 µm. f) to h): surface profile measured by white light interferometry for f) 3D printed lens, g) Edmund lens and h) Thorlabs lens, respectively. i) to k): extracted line profiles corresponding to the dashed lines I and II in f) to h) for i) 3D printed lens, j) Edmund lens and k) Thorlabs lens, respectively. l) to n): Images of USAF 1951 resolution target acquired under 532 nm (green light) illumination using l) 3D printed lens, m) Edmund lens and n) Thorlabs lens, respectively.
