TFOSC

TFOSC is a direct imaging and a low-medium resolution spectrometer. Its optical design is similar to the FOSC series ( see http://www.astro.ku.dk/~per/ ) but it has been modified and optimised by TUG for the 1.5-m telescope. It will also have a calibration unit (CALU). (See the attached drawing for the positioning at the cassegrain focus, but, however, the relative placement has been changed slightly since this drawing was made). TFOSC's mechanical design is almost complete. The calibration unit is being designed.
