Scientific paper

For the Very Large Telescope (VLT) Near Infrared (NIR) camera, a cryogenic shutter was developed for a 12 mm wide beam path with a 5 ms switching time and a 75 mW rate of power input. The control software was modified for use in the NIR camera. In the case where no parallel interface is available at the control computer, a control slide is provided for, on which a microprocessor produces the control signal for the sequence. The new shutter concept shows great advantages over the previous scanner drive of the SHARP (System for High Angular Resolution Pictures) camera. The stepping motor causes notably less vibrations than the scanner drive and less power consumption.
