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 ...

Basics of Lamp-Pumped Solid State (LPSS) Lasers As the trailblazer for many modern day laser designs, LPSS lasers are a mature technology that have been around since the invention of the first laser. The ...

Introduction to Diffraction Gratings Diffraction gratings are optical components that diffract and separate light into several beams at different angles by wavelength. Their working principle is hinged ...

Introduction to Ultrafast Lasers The ultrafast laser is a category of laser that emits ultrashort light pulses with time spans of femtoseconds or picoseconds. To put this in perspective, ultrafast lasers ...
