Right Angle Glass Prism

Prism pleasure

I bought several prisms to sit on a kitchen windowsill that gets morning sun. On a bright day, I have various spectra that move around the room, sometimes appearing in surprising spots, then stretching or fading. Just fun.

Glass Prism

I am pleased with the quality of this prism and would recommend it for anyone who has a sunny window sill to place it, and wonder at the phenomenon.
