Abstract:
A tunable filter includes: a first transparent substrate including a first reflective surface; a second transparent substrate including a second reflective surface that opposes the first reflective surface; and a supporting member, connected to the first transparent substrate, that supports the second transparent substrate on the first transparent substrate so that the second reflective surface is disposed at a position separated from the first reflective surface in a normal direction of the first reflective surface. A cavity between the first reflective surface and the second reflective surface forms an etalon. A relative position of the second transparent substrate with respect to the first transparent substrate changes due to thermal expansion of the supporting member, and a length of the cavity changes in the normal direction.

Claim (Index 1):
A tunable filter, comprising:\n a first transparent substrate including a first reflective surface; a second transparent substrate including a second reflective surface that opposes the first reflective surface; and a supporting member, connected to the first transparent substrate, that supports the second transparent substrate on the first transparent substrate so that the second reflective surface is disposed at a position separated from the first reflective surface in a normal direction of the first reflective surface, wherein a cavity between the first reflective surface and the second reflective surface forms an etalon, a relative position of the second transparent substrate with respect to the first transparent substrate changes due to thermal expansion of the supporting member, and a length of the cavity changes in the normal direction, the supporting member comprises:\n a base plate that extends along a back surface of the first transparent substrate, wherein the back surface of the first transparent substrate is a side opposite to the first reflective surface; \n a side wall that extends from a position corresponding to the back surface of the first transparent substrate toward the second transparent substrate to a position corresponding to a back surface of the second transparent substrate, wherein the back surface of the second transparent substrate is a side opposite the second reflective surface; and \n an upper wall that extends along the back surface of the second transparent substrate, \n the supporting member extends from a connection with the first transparent substrate toward the second transparent substrate, to a position separated farther from the first transparent substrate than the second reflective surface, \n the back surface of the first transparent substrate is connected to the base plate of the supporting member at a position separated from the second transparent substrate by the first transparent substrate, and \n the back surface of the second transparent substrate is connected to the upper wall of the supporting member at a position separated from the first transparent substrate by the second reflective surface.
