Description
Hand held simplest form of spectroscope. It can be used to get a general idea of the correlation between wavelength and observed color. A diffraction grating is used which spreads the incident light into its component wavelengths. An illuminated reference scale against which the spectrum may be viewed is also provided.
Features
Function: It is used to analyze light by splitting it into a rainbow spectrum. This can reveal spectral lines, such as the mercury lines in fluorescent bulbs. Design: The device is a handheld, simplest form of a spectroscope. It is a pocket diffraction spectroscope.
Educational Use: It is suitable for educational purposes like science fairs, for hobbyists, or for identifying gem treatments.
