置。(1) A pair of movable barrels are slidably and sealingly fitted to both ends of a fixed barrel having a pinhole in the center, and a lens assembly is attached to the outer end of each movable barrel via an O-ring. An aperture that is formed by fitting a three-dimensional body into the interior in a sealed manner, and allows the direction of the optical axis to be adjusted by slightly moving the lens assembly to an arbitrary angle with respect to the movable cylinder in a sealed state using an optical axis adjustment mechanism. In the filter, a plurality of through holes are formed in a radial direction on the movable cylinder side below the fitting and overlapping part of the lens assembly with respect to the movable cylinder, and each through hole has a slight gap between the fitting and overlapping parts. A lens assembly in a spatial filter, characterized in that a support rod is inserted whose tip is brought into contact with the outer peripheral surface of the lens assembly in order to maintain the gap and prevent the O-ring from collapsing in the core part. Three-dimensional sealing device.
