Miniature Microscope Design And Construction Based On Tilted Rotationally Asymmetric Printed Lenses
… The printed lenses were patterned using grayscale lithography in a custom engineered photosensitive hybrid sol-gel glass material. Illumination was delivered by high-brightness Light Emitting Diodes (LEDs) via multimode fiber. The design incorporated a custom imaging detector and a …
