| 英文摘要 | PURPOSE:To simplify assembling the mounting work and irradiate layer with high accuracy by resin-encapsulating a semiconductor laser element fixed with a fixing base together with an optical detector, and installing a diffraction grating for radiation laser light to the top. CONSTITUTION:A semiconductor element 1 is fastened with a fixing base 2 where a photodetector 4 is mounted. When resin 10 is sealed after interconnection, an uneven pattern 9 which diffracts laser light 3 in a required direction is formed on a mold 8. A grating pattern 9' is transferred to the resin 10 by compressing the mold 8, responding with an optical path, which competes the process. This construction makes it possible to minimize the number of components, simplify an assembling process and obtain a high accuracy laser light irradiation device. |
