A very beautiful piece of glass, high quality, I love it!
These are not prisms, they are diachronic glass cubes, reflecting only two colours out of two orientations (so four colours per cube, but only 2 at once). Flashlight, not so much, but sunlight through a window and they pitch a well-saturated beam 15 meters across the room nicely.
Dichroic X-Cube Glass Prisms 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. That is, certain surfaces within the prism act as dichroic filters. These are used as beam splitters in many optical instruments, like LED projectors.
Nice and very clean glass prisms. Good size
Have fun kids
