The Mid-infrared E-ELT Imager and Spectrograph, or METIS, is foreseen as an early instrument for the European Extremely Large Telescope (E-ELT). A key part of METIS is the Cold Chopper (MCC) which switches the optical beam between the target and a ne

This paper discusses the development, realization, and characterization of a demonstrator cryogenic chopper for METIS, the third instrument on the ELT. The chopper has to tip/tilt in 2D with a combined angle of up to 13.6mrad and achieve a 95% duty c
