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.

A dichroic prism splits light into two beams of differing wavelength (colour). A trichroic prism assembly combines two dichroic prisms to split an image into 3 colours. They are usually constructed of one or more glass prisms with dichroic optical coatings that selectively reflect or transmit light depending on the light's wavelength.
