Isotropic and Anisotropic

Isotropic and Anisotropic

1. Isotropic

   • Crystal systems
     • Cubic
     • Amorphous
   • Non-directional optical properties
     • behaves the same in any direction
   • Diamonds
   • Spinel
   • Garnet
   • Fluorite
   • Singly refractive

2. Anisotropic

   • Crystal systems
     • Hexagonal
     • Tetragonal
     • Trigonal
     • Triclinic
     • Monoclinic
     • Orthombric
   • Light enters anisotropic material
     • Light is forced into two seperate rays
       • Light travels at right angles to eachother + at different speeds
         • Light that has been made into 'tidy' rays of light = Polarized light
           • Polarized light
             • Light has billions of light waves
               • No order to these light waves = Non-polarized light
