Fabrication of Shape Controllable Micro-Lens Arrays by Drop on Demand Printing on the Glass Micro-Holes Arrays

Abstract:

A simple and easy method is demonstrated for the fabrication of the shape controllable micro-lenses, which are widely used in biomedical systems for improving the image quality as their ability to efficiently focus light into the devices. The micro-lenses were drop on demand printed on the glass micro-holes based on a simple drop on demand printing technique. The shape controllable micro-lenses with a fixed diameter resulting from boundary confinement effect of the micro-holes and the surface wetting conditions are controlled by printing different numbers of drops per micro-lens. The influence of the geometrical shape changes on the optical properties is also investigated. The micro-lens array with different numerical apertures (NA) can be fabricated by controlling the number of drops of the micro-holes as the boundary confinement and hydrophobic effect of the micro-holes.
