伝送距離や方向に大きな制限を受けることになる。Conventionally, a KH1 converts the cross-sectional shape of Rade light into a linear shape for the various purposes mentioned above. As shown in FIG.
By making the laser beam incident on a compound lens consisting of -, each cylindrical beam, eb-, etc., the Radhe light was focused in a straight line and irradiated onto the workpiece d. However, this method requires a compound lens 6 with a complicated structure, which increases the cost, and the cross-sectional shape of the radar light output from the oscillator is circular. , when the Rade beams Ll1 are focused by the combining lens, a problem arises in that the lengths of the Rade beams that are linearly focused by each semi-cylindrical lens b are not equal, as shown in FIG. Furthermore, by using the compound lens 1, the Rade light output from the Rade oscillator a is made incident on the entire surface of the multiple lens/@ through an optical fiber, for example, since the transmission distance and direction of the Rade light are 1111. will be subject to significant restrictions.

できるなど実用上極めて有用である。As described above, the present invention focuses the Rade light output from the Rade oscillator using an optical system, makes it enter the transparent plate-like body from one end surface, and causes it to diverge and exit from the other end surface. Radhe light with a straight cross section is obtained at a position away from the emission end face. Therefore, it is possible to obtain multiple linear Lehde beams without using a compound lens that combines multiple semi-cylindrical lenses with complex shapes as in the past, and the length of the multiple linear Lehde beams can be made uniform. can be pressed. Furthermore, since it is possible to obtain linear Rade light by inputting nine Rade lights output from a laser oscillator into a transparent plate using an optical fiber, the Rade light from the Rade oscillator is not limited to a medium distance in the direction. It is extremely useful in practice, as it can be transmitted to
