Abstract:
1. An optical apparatus comprising: a first optical element; a first supporting device that supports the first optical element; a second optical element; and a second supporting device that supports the second optical element, wherein each of the first and second supporting devices comprises: wherein each of the plurality of members is configured such that a rigidity thereof in a first direction inclined relative to a direction orthogonal to an optical axis of the corresponding one in a plane including the optical axis is lower than a rigidity thereof in each of two directions that are orthogonal to the first direction and that are orthogonal to each other, and wherein the apparatus has a material and an arrangement thereof such that an amount of change in an optical characteristic due to a displacement amount of the first optical element in a direction of an optical axis of the first optical element per a unit amount of change in temperature is cancelled at least partly by an amount of change in the optical characteristic due to a displacement amount of the second optical element in a direction of an optical axis of the second optical element per the unit amount of change in temperature.
