    • PROBLEM TO BE SOLVED: To provide an optical measuring device capable of realizing higher integration efficiency, and reducing the cost.
      SOLUTION: In a hemispherical integrating sphere according to one embodiment, a mirror generating mirror reflections (regular reflections) is not used for the entire plane part, but rather adopts a material that generates regular reflections is adopted for the outer peripheral side (hereafter, referred to as "outer peripheral part") of the planar part, and a material having at least a higher reflectance in an ultraviolet wavelength band, in comparison with the material for the outer peripheral part is adopted for the inner peripheral side (hereafter, referred to as "inner peripheral part"). The material adopted for the inner peripheral part is less expensive and has higher reflectance in the ultraviolet wavelength band, in comparison with the material adopted for the outer peripheral part. The hemispherical integrating sphere having a high integration efficiency (les light absorption) with reduced cost can be acquired, by arranging the outer peripheral part and the inner peripheral part in a proper range by using respective appropriate material.

    • 要解决的问题:提供能够实现更高的集成效率并降低成本的光学测量装置。 解决方案:在根据一个实施例的半球形积分球中,对于整个平面部分不使用镜面反射镜反射(正反射),而是采用产生规则反射的材料用于外周侧( 以下称为“外周部”),与内周侧(以下称为外周部)相比,在紫外线波长带中至少具有较高的反射率的材料 ,称为“内周部”)。 与外周部使用的材料相比,内周部使用的材料成本较低,紫外线波长带的反射率较高。 通过使用适当的材料将外周部分和内周部分布置在适当的范围内,可以获得具有降低成本的高集成效率(les光吸收)的半球形积分球。 版权所有(C)2011,JPO&INPIT
