ナキューブ保持枠に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner cube holding frame used for a laser interferometer or the like, and more particularly, to a fitting of the corner cube with the entrance / exit surface facing the front. The present invention relates to a corner cube holding frame that is inserted into a hole and held by the holding frame in a state in which a peripheral portion of an input / output surface is in contact with a receiving surface perpendicular to an optical axis formed on an inner flange portion of a fitting hole.

していた。In the conventional corner cube holding frame as described above, the corner cube is bonded to the outer peripheral surface of the cylindrical portion and the inner surface of the holding frame fitting hole or the peripheral edge of the input / output surface and the receiving surface of the fitting hole inner flange portion with an adhesive. In this case, a pressing member provided so as to protrude into the holding frame fitting hole holds the pyramid portion of the corner cube by pressing a portion close to the cylindrical portion of each slope.

干時間が掛かる、と言った問題がある。The holding frame using an adhesive has a simple structure, but since the corner cube must be pressed against the receiving surface of the holding frame until the adhesive is cured, it takes a long time to assemble, and the curing of the adhesive takes place. In this case, gas is liable to be generated, and the adhesive leaks out on the inclined surface of the pyramid or the entrance / exit surface, so that the usable area of the corner cube is easily reduced.The corner cube cannot be removed, so the corner cube cannot be replaced. It is difficult to clean, the linear expansion coefficient of the adhesive is as large as about 10 -4 K -1, so if there is a temperature change, the corner cube is easily displaced or distorted, and the adhesive is easily peeled off, There is a problem that said. On the other hand, the holding frame using the pressing member does not use an adhesive because it does not use an adhesive, but the structure is complicated because the pressing member that presses each slope of the pyramid portion of the corner cube is complicated, and the manufacturing is difficult. The cost increases, the reflecting surface of the corner cube shrinks the air interface by the pressing member, the total reflecting surface is reduced, the pyramid surface is easily distorted by the pressing force of the pressing member, and it takes a little time to assemble, There is a problem that said.

内に固定する。The corner cube 2 is formed by cutting the top of a pyramid portion at a plane perpendicular to the optical axis, and providing a mutually perpendicular surface and an obtuse cut surface 2a of the pyramid portion.
The input / output surface 2b is inserted into the fitting hole 1a until it contacts the receiving surface 1b perpendicular to the optical axis of the inner flange portion that protrudes into the fitting hole 1a of the holding frame main body 1. Next, the lid-shaped pressing member 3 in which the spherical elastic member 4 is fitted in the central hole of the inner surface in a state of protruding from the inner surface is fitted into the fitting hole of the holding frame body 1.

る。The cut surface 2a of the corner cube 2 can be easily formed by press molding or subsequent processing, and there is no room for the chipping or dripping which is likely to occur at the top portion when the reflective surface of the pyramid is polished. Increase the rate. Then, as described above, the corner cube 2 is inserted into the fitting hole 1a via the spherical elastic member 4 by the pressing member 3 screwed into the fitting hole 1a.
By fixing the inner cube 1a, it is easy to assemble and exchange the corner cube 2 and remove it for cleaning, without applying excessive pressure to the corner cube 2 and equalizing the stress of the corner cube 2. Therefore, the reflecting surface is not distorted, and even if there is a temperature change, the corner cube 2 does not rattle or is distorted, and the elastic member 4 contacts the pyramid portion of the corner cube 2. There is no reduction in the reflective surface because there is no
Limited to 2a only. However, the same effect can be obtained regardless of whether the pressing member 3 is removably press-fitted into the fitting hole 1a or the elastic member 4 has a cylindrical or prismatic shape.

It is a hole for rotation when screwing into and out of the fitting hole 1a, and is also a hole through which air flows. But,
Since the air can be distributed from the screw section, etc.
When a hole for rotating the pressing member 3 is provided so that dust or the like does not enter the fitting hole 1a, it is preferable to use a bottomed hole.
Needless to say, means other than the hole can be used to rotate the pressing member 3. As the elastic member 4, a member made of a synthetic resin, particularly a member made of a fluorine resin such as an ethylene tetrafluoride resin is preferably used because of its excellent durability.

に得られる。The holding frame main body 1 in the illustrated example is attached to a holding frame mounting surface of an optical device, has a flange portion for mounting to the optical device outside the fitting hole 1a, and has a mounting screw on the flange portion. Is provided, and the surface on the fitting hole 1a side of the mounting flange portion is formed on the same plane as the receiving surface 1b, and serves as a contact surface 1d that contacts the holding frame mounting surface of the optical device. ing. Then, the holding frame main body 1 is attached to the optical device by screws in a state where the contact surface 1d is in contact with the holding frame mounting surface of the optical device. Therefore, even if the holding frame body 1 is made of a normal metal material having a linear expansion coefficient of about 10 −5 K −1, the position of the entrance / exit surface 2 b of the corner cube 2 is always the optical device regardless of the temperature change. Coincides with the mounting surface position. This effect is obtained when the mounting flange portion of the holding frame body 1 receives the surface on the side opposite to the fitting hole 1a.
Even if it is formed on the contact surface on the same plane as 1b, the same can be obtained.

な測長を行うことができる。In the optical device shown in FIG. 4, the laser beam from the stabilizing laser 5 is split into two by the beam splitter 6, and the reference beam reflected by the corner cube 21 having the fixed reference optical path and the corner cube 22 moving the measuring optical path, respectively. The light and the measuring light are combined and incident on the light receiving element of the interference fringe counting wavelength circuit 9, and the interference fringe counting and measuring circuit 9 counts the interference fringes and measures the optical path length of the measurement optical path. It is a length measuring instrument. The corner cubes 21 and 22 are held by the holding frame body 1 in the same manner as the corner cube 2 shown in FIGS. 1 to 3, and the holding frame body 1 holding the corner cube 21 is attached to the holding frame perpendicular to the reference optical path of the fixing member 7. A moving member 8 which is attached with the contact surface 1d in contact with the surface 7a and in which the holding frame body 1 holding the corner cube 22 moves in the direction of the arrow in parallel with the measurement optical path.
The mounting surface 8d is attached to the holding frame mounting surface 8a perpendicular to the measurement optical path. Therefore, even if there is a temperature change, the incident surface positions of the corner cubes 21 and 22 always correspond to the position of the holding frame mounting surface 7a of the fixed member 7 and the position of the holding frame mounting surface 8a of the moving member 8, respectively. Length can be measured.
