Abstract:
A temperature adjustment apparatus for adjusting a temperature of an object to be temperature-controlled, said apparatus comprising:a first temperature adjustment mechanism for controlling the temperature of the object to be temperature-controlled, directly, with a fine temperature control response; and a second temperature adjustment mechanism for controlling the temperature of the object to be temperature-controlled, directly, with a coarse temperature control response; a controller for controlling at least one of the first temperature adjustment mechanism and the second temperature adjustment mechanism, based on a temperature measurement result of the object, wherein said first and second temperature adjustment mechanisms have different temperature control responses, and said controller controls the temperature of the object to be temperature-controlled in cooperation with coarse adjustment and fine adjustment, on the basis of a difference between the temperature control responses, and wherein the object to be temperature-controlled by the first temperature adjustment mechanism and the object to be temperature-controlled by the second temperature adjustment mechanism, are identical.
