About This Product
With prisms or diffraction gratings, the unit gives bright, clear spectra from red through to violet, and no blackout is needed. Its plug-top supply stops the voltage being suddenly raised, avoiding the blown bulbs that can occur with a traditional ray box on a variable supply. An LED.white Experiment Kit and an Acrylic Light Pipe are available separately. Besides buyers across India, the LED white with Light Guide Demonstrator can be exported to institutions in Luxembourg, São Tomé and Príncipe, Oman, Sierra Leone, Slovenia and Mauritania.
