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 ...

What is Electro-Optics? In the last 20 years or so, the field of electro-optics has become increasingly important. It is often challenging to predict the future of scientific discoveries and their relevant ...

In our prior blog post we discussed the properties and major uses of Antireflective Coatings. We also talked about how how anti-reflection is not a property of materials. Rather, it is a consequence of ...

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 ...

Polarization As A Property of Light Conversation about light waves typically focuses on frequency, wavelength, or intensity. Many introductory physics courses cover these concepts in great detail so that ...

Introduction X-rays are one of the most versatile forms of radiation.  The rays can penetrate thick objects without absorbing or scattering, rendering them extremely useful for imaging purposes. X-ray ...

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 ...
