Abstract

PURPOSE:To enable to easily make the axes matched and elevate the productivity, by using a single mode optical fiber for three optical fibers of the cross-shape light distributor, and using a multimode optical fiber for one monitor optical fiber. CONSTITUTION:A projection light beam from the optical fiber 1 of the input side becomes a parallel flux of light by the lens 2, and is divided into a transmission light beam and a reflection light beam by the half mirror 5. The transmission light beam is condensed by the lens 6, is made incident to the optical fiber 7 of the output side, and the reflection light beam is made incident to the monitor optical fiber 9. On the other hand, a projection light beam from the optical fiber 3 of the input side is made incident to the optical fiber 7 through the lens 4, the half mirror 5 and the lens 6, and also is made incident to the monitor optical fiber 9 through the half mirror 5. By using a single mode optical fiber and a multimode optical fiber for the optical fibers 1, 3, 7, and the monitor optical fiber 9, respectively, it is possible to easily match the axes and elevate the productivity.
