Product Details

Studying the spectral lines of a light source

The spectrometer is used to study the spectral lines of a light source.

Easy to use and robust, this instrument is particularly suitable for classrooms.

Altay’s Spectrometer allows to detect the spectral lines with precision and to measure the corresponding wavelength.
