Trichroic Prism

Description:  A trichroic prism splits light into three beams of light with different wavelengths (or colors). These prisms are used in some video cameras to send different colors of light to different color sensors. The prisms are coated with special coatings to filter and transmit different wavelengths of light. This device could be used to investigate interactions of light with various materials to in increasing complexity K-12.
