Now, this was a fun model to build. The superstructure was soldered brass to support the visible components. The model body had to rotate and the mirror had to pivot. The point of this display was to show the process of taking white light and separating it into its component colors.
Colored acrylic rods are used to show the lights path off of the reflector and through various mirrors and colored lenses. Each color then goes through it’s individual “reader” and the information gathered is sent back to earth. This is a classroom and exhibit model to show this process. I am a big fan of hands-on education.
