AstroMedia: The Handheld Spectroscope

A high-precision transmitted-light diffraction grating with 1,000 lines per millimetre makes the spectral colours appear. In this way, the hand spectroscope enables the investigation of different types of light, from the continuous spectrum of glowing bodies such as the sun or a light bulb to the line spectra of fluorescent lamps and many other light sources.

On a brightness-adjustable scale, the wavelength can be read to an accuracy of approx. 5 nanometres.
