3D Printed Plano-convex Lens

Chinese researchers have developed a method for 3D printing plano-convex lenses using photosensitive resin that can focus THZ radiation. This radiation can be used in advanced security scanners, manufacturing quality control, medical imaging, and even high-speed communications.

Below is a look at some of the researchers' setup. What could this mean for a variety of imaging techniques going forward? Any thoughts?:
