Spectrum Projector (LSE) Spectrum Projector Experience a clear and bright projected spectrum in a room that cannot be completely darkened and demonstrate the changing color of an incandescent object as its temperature changes with simple equipment. The spectrum projector includes all of the materials necessary to build a device that will produce a diffracted beam of light in two directions (two lab setups in one). A dimmer allows students to vary the temperature and brightness of an incandescent light bulb to study how the spectrum changes. A paraffin spectrum analyzer will show the students a bar graph of the projected spectrum. They can experiment with how objects of different colors appear in different colors of light. The kit contains: 2 squares of diffraction grating • 2 cardboard tubes • 2 collimated lenses (53mm diameter) • 1 200-watt clear light bulb • 1 socket with dimmer, lampholder cage, and power cord (assembly required) • 1 set of paraffin blocks • 1 set of small mirrors • 6 bottles • red, blue, and green felt (2 sheets of each) • 4 filter sheets (6" x 6") • 1 set of instructions Qty :
