Beamsplitter Cubes

White light strikes a pair of beamsplitter cubes with anti-reflective coatings for infrared light. These coatings separate white light into its constituent colors. The surrounding lab environment was darkened to highlight the mesmerizing colors captured in this picture with a cellphone camera. The texture of the sheet of paper on which the cubes were placed can be seen on the front of the image.
