Engineers at Harvard University have published their proposal for a large area lens design that addresses the high-demand of the technological age. With a nod to Moore’s Law, they sought to unify two ...

A new study presents a novel approach to imaging the human cornea. The research team at the Langevin Institute in Paris says their optical coherence tomography device is the first capable of full-field in ...

Having discussed the history and physics of AR coats, our final article discusses the standard AR coating techniques via application of thin films. The basic principles of AR coating application remain the ...

Photonics Technologies in Farming Farmers everywhere face the same daunting task: the world population is growing at an exponential rate, and food supply has to keep up. There is practical limits to a ...

Introduction Everyone knows or heard about UV or anti-reflective coatings on lenses and filters but what are they really and what distinguishes anti-reflective coatings from other types of coatings? We ...

Introduction to Adaptive Optics Anyone who has ever driven down the road on a hot day has probably noticed steam radiating off the pavement. However, if you looked closely enough, the steam was actually ...

Introduction to Spectroscopy Imaging We have discussed many applications of spectrometers, but how do we attain the final spectral image to analyze? Spectrometers contain varying types of imaging systems ...

Introduction to Prisms Even as early as in the 13th century, six-sided crystals of natural quartz were used to generate rainbows. In the late 1660s, people believed that color was a mixture of lightness ...

Basics of Operation There are many different types of lasers available in todays photonics market, however, Diode Pumped Solid State (DPSS) laser systems are a reliable and widely-used technology. Simply ...

What is Hyperspectral Imaging? Imagine an iPhone app that could help you choose the best produce, the ripest fruit, or determine if the vegetables you are about to buy are truly organic. Well, it turns out ...
