Spectroscope Low Cost

Product Description

The performance of this ultra-low cost spectroscope is comparable with instruments typically costing ?80. It uses a CD or DVD as a reflective diffraction grating and clearly shows Fraunhofer lines in the spectrum arising from natural light ¨C and distinctive emission bands from artificial sources such as sodium lamps. Differences between fluorescent lighting tubes ¨C e.g., white light or ¡®warm¡¯ light types – can be easily identified by their distinctive emission bands.
