A 2D spectrometer suitable for solar observations of high spatial, spectral, and temporal resolution was built and successfully tested with the German Vacuum Tower Telescope at the Observatorio del Teide/Tenerife. Using a universal birefringent filter and a Fabry-Perot interferometer (FPI), arrow-band (less than about 30 mA) filtergrams can be obtained. With this instrument, it is possible to scan through a Fraunhofer line at an appropriate number of wavelength settings within a few seconds, Here, fast scanning is accomplished by tuning only the FPI. The images are taken by two CCDs. One of them is coupled with an image intensifier to achieve short integration times. Due to the instrument's design, the adequate field of view has a diameter of about 20-40 arcsec. The spectrometer can be tuned to virtually any wavelength in the visible spectrum.
