Scheimpflug principle
The "plane of sharp focus" can be changed so that any plane can be brought into sharp focus. When the DMD plane and lens plane
are parallel, the plane of sharp focus will also be parallel to these two planes. If, however, the lens plane is tilted with respect to the
DMD plane, the plane of sharp focus will also be tilted according to geometrical and optical properties. The DMD plane, the principal
lens plane and the sharp focus plane will intersect in a line below the projector for downward lens tilt.
TEC
Thermoelectric cooling uses the Peltier effect to create a heat flux between the junction of two different types of materials. A Peltier
cooler/heater or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the
other side against the temperature gradient (from cold to hot), with consumption of electrical energy. Such instrument is also called
Peltier device, Peltier diode, Peltier heat pump, solid state refrigerator or thermoelectric cooler (TEC).
