INTOPS stands for International Operations (as far as I know) and is a name given to the Danish Leopard 2A5 upgrade for use in Afghanistan (mine protection kit, Barracuda camouflage, air conditioning unit, slat armor, etc.).
SPECTUS is a night vision system for the driver using thermal cameras and image intensifiers (and if required fuzing both images together) made by Hensoldt. It has been adopted on the Leopard 2A6MA2 and is part of the Leopard 2A7V upgrade. As one can see in the photographs, the Danish Leopard 2A7 tanks do not feature the SPECTUS system.
