When we begin learning about light, we usually start by talking about the colors of the spectrum and the fact that white light can be broken up, or dispersed into a spectrum of colors. To disperse light into its spectrum, Sir Isaac Newton used a prism. However, in recent years the diffraction grating has replaced the prism for this purpose because it is easier, more effective, and less expensive. We offer Single Axis and Double Axis Diffraction Grating, and Double Axis Prism Glasses. For more accurate spectral observations, try our Hand-Held or Pocket Spectroscope. If you're looking for some interesting lights to observe, we have the amazing ColorFlame Birthday Candles.
