In this easy to build device a high-precision light transmissive diffraction grating brings with 1,000 lines per mm, the spectrum for the appearance and allows the investigation of different types of light from the continuous spectrum of incandescent bodies like the sun or a light bulb up to the line spectra of fluorescent lamps etc. On a regulatable in the brightness scale the wavelength can be read to about 5 nanometers. The world's most affordable pocket spectroscope!
The measuring accuracy is different to a professional spectrometer below 3%.
Complete with diffraction gratings, magnifying lens, f +120 mm and nanometer scale.
Packaging: 300 x 210 x 5 mm
