| Triangular Prism: Place in the simulation window. It appears at a preset location. The triangular prism cannot move or rotate. The prism always appears in combination with a beam projector resting at a preset location. In Run mode, the prism refracts white light from the beam (if no filters are present), producing a multi-colored beam. If you delete the prism, you will also delete the projector. However, you can delete the projector without deleting the prism.
