Visible Ray Geometrical Table Top Optics Set - 28 Pieces

This system is modeled after the Hartl Optical Disc system, but does not need to be mounted vertically as it can rest horizontally on any flat surface. The ray box produces a variety of different thickness rays and number of rays which can then be created across the bench top disc with different optical components in the center to measure angles of refraction, distances, etc. Set includes (1) Ray box, (3) Ray slit cards to make light rays, (1) Open vessel to add fluids of different refractive indices, (1) 360 degree optical bench disk, (2) Acrylic triangular blocks, (1) Acrylic Semi Circle Block, (1) Rectangular Block, (1) Extra Bulb for ray box, (8) Various color filters, (3) Mirrors, (1) Convex lend, (1) Double convex lens, (1) Double Concave lens, (1) Color index card, (2) Half Frosted slides
