| 9B61.00 | Light Paths Made Visible | | |
| 9B61.20 | optical disc | Ob-8 | A ground glass disc makes rays of light more visible and has provision to mount various optical elements. |
| 9B61.20 | optical disc | L-6 | A description of the optical disc. |
| 9B61.20 | optical disc | O-4b | Many optical demonstrations can be shown with the optical disc. |
| 9B61.25 | blackboard optics | AJP 36(12),1170 | Several suggestions to improve the Klinger blackboard optics system. |
| 9B61.30 | smoke box | L-9 | A large glass fronted black box filled with smoke or ammonium chloride (A-5) fumes. |
| 9B61.31 | bee smoker | TPT 28(6),420 | Bee smokers produce a large amount of smoke from one wadded paper towel. 1-800-Beeswax. |
| 9B61.32 | beam splitting device | AJP 48(4),320 | Use a stack of microscope slides to obtain parallel, convergent, and divergent sets of beams. |
| 9B61.33 | conical beam in smoke box | AJP 49(12),1185 | A mirror set at a small angle on the end of a rotating shaft is used to produce a reflected conical beam. |
| 9B61.35 | chalk dust | L-10 | Clap dusty chalkboard erasers together. |
| 9B61.36 | laser mount for optics | AJP 43(1),92 | A mount for a laser permits either transverse or rotational movement of the beam. |
| 9B61.38 | gaussian beam | AJP 41(4),549 | A rotating device with two offset lenses generates a ray envelope from a laser beam that simulates a Gaussian beam. |
| 9B61.40 | gauze screen | L-8 | White threads are stretched 2-3 mm apart on a 2x4' frame. |
| 9B61.41 | tracing paper screen | AJP 30(12),929 | Use tracing paper on embroidery frames. |
| 9B61.50 | optical tank | AJP 33(11),970 | Fluorescein. in an aquarium, aerosol generator. |
| 9B61.50 | optical tank | L-7 | A 3x3x36" water tank with some fluorescein added. Many demos mentioned. |
| 9B61.61 | ink paths on the overhead | TPT 2(6),278 | Ink
dipped balls are rolled down chutes at various barriers shaped like optical
elements. The incident and reflected paths are traced out. |
| 9B61.66 | elastic string ray model | TPT 2(2),87 | Elastic strings don't sag like regular string when used in three dimensional ray models. |
| 9B61.71 | invisibility of light | L-5 | Light passing through a glass fronted black box is not visible until a white card is placed inside. |
