The Aurora Clock has been in production for over 40 years. There are continuously changing colors and surprising color ‘shifts’ when the secondhand disk overlaps the minute & hour hands, and the colors change depending on your viewing angle. The color changes have to do with polarized light and a phenomenon called bi-refractance. Vectors of light are being rotated as they pass through each material which is very different from color filtering.
The first Aurora clocks were made by Rathcon and called the Spectrum. Then they were manufactured by Kirsch-Hamilton. Next, in the late 80’s, Hampton Haddon had a version made in Japan, but abandoned the clock around 1991. In 1993 we at ChronoArt started manufacturing Luminas (a different polarized light clock) and then a year later started also manufacturing new Auroras.
