Lens A on the left is a double convex lens with a long focal length. Lens B is also a double convex lens, but it has a shorter focal length. Lens C, on the right, is a double concave lens.

Optics Kit Experiments Optical FiberOptical fibers are being used extensively in the telecommunications world; in fact, most of our phone lines have been replaced by optical fibers. Included in the Kit is a small section of fiber. Look through one end of the fiber while you shine a light into the other end. Try out your optical fiber at

Read more about properties of optical fibers at Diffraction GratingThe diffraction grating in the Optics Discovery Kit can be used to break white light into a spectrum. Try looking through the grating at a bright light source. Be sure you have the correct orientation! Find out more about the diffraction grating and what it can be used for in the

Optics Kit Experiments PolarizersMost light is polarized in some direction. Polarizers transmit only that light which is oriented in a certain way. As you can see above, if you turn polarizers 90° to each other, they will transmit little or no light. Test out your polarizers at the

Optics Kit Experiments MirrorWe use mirrors so often that we usually take them for granted. The mirror in the Optics Discovery Kit is made of a special material called mylar which has been aluminized, much like regular glass mirrors. This mirror, however, can be bent into both a convex and a concave shape. Learn more about mirrors at the

Optics Kit Experiments PrismThe prism enclosed in your kit, is not actually a part of the Optics Discovery Kit made by the Optical Society of America, but we added it because we believe it to be an interesting and useful tool in the study of light and optics. We can use the prism, like the diffraction grating to break white light into a spectrum. Find out how prisms are like diffraction gratings at the
