CCD Linear Camera (230 V, 50/60 Hz)

Experiment topics

Spectrometer

Investigations of
- Emission and absorption spectra
- Transmission curves of filters
- Spectral resolution of white light Wave optics

Display and measurement of diffraction and interference spectra, for example, diffraction at a slit, pinhole, grating, Newton's rings, Fresnel mirrors; comparison of measured spectra with theoretical calculations.

Geometric optics For example, measurement of focal lengths, enlargements and divergence of a light beam. Time-dependent data acquisition For measuring light modulation on a pixel, for instance, oscillations of monochromatic light sources, measurement of doublets in emission and absorption spectra (e.g. sodium, mercury). Fast Fourier transformation allows wavelengths to be determined.
