| Klinger Blackboard OpticsT Accessory set, which includes the Multiple Ray Projector, expands the number of experiments possible with the basic optics set by introducing necessary components to explore color, dispersion, magnification, advanced focal length and virtual image experiments. Lenses of various focal lengths, slits, diffraction grating, polarizing filters, and prisms are included for demonstrations such as the telescope, microscope, camera, and eye defects. When the Diffraction Grating is used with the Fluorescent Screen, both the visible spectrum and a portion of the ultraviolet can be observed. In addition, it is possible to demonstrate reversal deviation angles in the colors of the spectrum. |
