Researchers at the Harvard John Paulson School of Engineering and Applied Sciences demonstrated a titanium dioxide planar lens capable of resolving nanoscale features. The technology could replace convention multi-element optical design and can be scaled for mass production in foundries which produce semiconductor devices.
The technology could potentially be used to creatie light weight wearable vision systems or replace complex multi-lens designs in microscopes, telescopes, and camera lenses.
Curved lenses, like those in cameras or telescopes, are stacked in order to reduce distortions and resolve a clear image. That’s why high-power microscopes are so big and telephoto lenses so long. While lens technology has come a long way, it is still difficult to make a compact and […]
