Direct-view spectrometer DV-90 129-380 1 unit

This is a small direct viewing spectroscope that makes it easy to observe continuous and bright line spectra and Fraunhofer lines. It is possible to observe continuous spectra, emission line spectra, and Fraunhofer lines. The dispersion length at the clear viewing distance is about 40 mm, and the spectral lines are clearly distinguishable. The D-100 model is equipped with a comparison prism, allowing two light source spectra to be observed side by side. Slit: 4mm wide Dispersion length: approx. 40 mm Product code: 129-380
