Abstract
An optical element holding apparatus provided with a holding portion for holding a flange portion of an optical element. The holding portion includes a bearing surface block having a bearing surface, which contacts the flange portion, and a bearing surface block support mechanism, which rotatably supports the bearing surface block about a tangential axis of the optical element. This structure holds the optical element with the optical element holding apparatus in a kinematical manner and maintains satisfactory imaging performance in the optical element.

63. A holding apparatus comprising:
-
a holding mechanism communicated with a member to be held, wherein the holding mechanism includes;
three flexure members connected to the member to be held, wherein the three flexure members hold the member to be held at three locations; and
first and second manipulators connected to at least one of the three flexure members, wherein the first and second manipulators manipulate at least one of the three flexure members, such that manipulation of the first manipulator causes at least one of the three flexure members to move the member to be held in a first direction and such that manipulation of the second manipulator causes at least one of the three flexure members to move the member to be held in a second direction that differs from the first direction. - View Dependent Claims (64, 65, 66, 67)
