Order No. 406.HSP

In this easy to build device, a high-precision transmitted light diffraction grating with 1,000 lines per mm makes the spectral colours appear and thus 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, etc.
On a scale with adjustable brightness, the wavelength can be read with an accuracy of approx. 5 nanometres.
The world’s cheapest handheld spectroscope! The deviation from the measuring accuracy of an expensive professional spectrometer is less than 3%.

Complete with diffraction grating,
Magnifying lens f +120mm
and nanometer scale.
Packaging: 300 x 210 x 5 mm
