The optical system for light condensing convergence which uses the type concave mirror on the axis

摘要

(57) Abstract This invention has the 1st refractor which is laid out in one side of the emission line source and the target which is laid out on opposite side of the emission line source, it consists of the light condensing convergence system of radiation. The 1st refractor has the concave condition reflected surface part, desirably, that concave condition reflected surface part the whole surface of the refractor it should have consisted of. Paralleling to the optical axis and that optical axis, is laid out it has possessed the 1st center of curvature where as for the concave section of the 1st refractor, it is desirable, to consist of the abbreviation toroidal aspect. The electromagnetic line source, on the optical axis, from the center of curvature just 1st distance slipping in axial direction facing toward the concave section, being abbreviated and being laid out. The target the single optical fiber or like the optical fiber flux electromagnetic radiation from the source which is reflected by the concave section converging substantially, in order image formation to be done, on the optical axis, in the direction which leaves from the concave section from the center of curvature just 2nd distance slipping in axial direction, being abbreviated and being laid out. At the time of this constituting, 1st and 2nd distance (1zs/r1) (1zi/r1) =1 satisfies formula approximately. However, as for zs 1st distance, as for zi 2nd distance, as for r1 when using for the part compensation of aberration the toroidal refractor, it is 1st radius of curvature of the toroidal reflected surface part of the 1st refractor. In addition, in order furthermore to improve the light condensing tonnage as another execution feature, opposing with the 1st refractor, and it is possible to provide the 2nd refractor on back of the electromagnetic line source. This system furthermore may be constituted by the housing which has the flank which possesses the inside which forms the 1st and 2nd refractor furthermore as another execution feature.
