Figure 6: Lens curvature profiling and imaging.
From: Design and fabrication of a passive droplet dispenser for portable high resolution imaging system
(a) Curve tracing of the front surface of three silicone lenses fabricated using the passive dispenser. (b) Gaussian fitting of the corresponding profiles and the calculated radii of curvatures. (c) Measured and calculated focal lengths plotted as a function of the volume of the harvested lenses. (d1–d4) Magnified images of the USAF target card of magnifications 30X, 50X, 80X and 25X respectively. (e1–e4) Images of an onion root tip at different magnifications.
