A thinner, flatter lens

Discovery should lead the way to lighter, less-bulky cameras, telescopes, and cellphones, SEAS researchers say

By Leah Burrows, SEAS Communications 

Curved lenses like those in cameras or telescopes are stacked to reduce distortions and clarify images. That’s why high-powered microscopes are so big and telephoto lenses so long. While lens technology has improved, it is still…

A better hologram for fraud protection and wearable optics

Holograms are a ubiquitous part of our lives. They are in our wallets — protecting credit cards, cash and driver’s licenses from fraud — in grocery store scanners and biomedical devices. Even though holographic technology has been around for decades, researchers still struggle to make compact holograms more efficient, complex and secure. Researchers at the Harvard John A. Paulson School of…
