In this chapter, we tie together the previous two chapters, Crystal Chemistry and Crystallography, by interweaving them with optics, resulting in two related disciplines: optical crystallography and optical crystal chemistry. Also included is a detailed discussion of how the polarizing light microscope is used to examine thin sections of minerals to aid mineral identification. The properties of light and its reaction with minerals are explained and visualized through animations.
Topics covered in Chapter 5 include:
• Macroscopic View of Polarized Light and Minerals
• Making a Thin Section
• Meet Your Microscope
• Wave Theory of LIght
• Optical Classes and Refractive Index
• Reflection vs. Refraction: Snell's Law
• Wavelength and Refractive Index
• Visual Representations of Refractive Index
• Birefringence and Retardation
• Interference Figures
The Mineralogy and Optical Mineralogy Series is specifically designed to take full advantage of digital media technology to empower students and teachers of mineralogy. Using color photographs, illustrations, movies, 3D models that can be rotated, interactive diagrams, and review questions, this series makes a challenging subject approachable. Also, each chapter in the series is available separately allowing the reader to pick and choose only those chapters they need for their specific course.
