Spectrometer 2

Function and Applications

The spectrometer can be used as both a grating spectrometer and a prism spectrometer. It enables the investigation of diffraction, refraction, and dispersion as well as the precise determination of wavelengths of spectral lines. Measuring spectra supports the understanding of atomic physics and fundamental principles of applied optics.

• Fine adjustment drives for the table and observing telescope allow backlash-free angular settings with an accuracy of half arc minutes
• Adjustable entrance slit for adaptation to different light intensities
• Observing telescope with crosshair for precise angle and line measurements
