    • An infrared optical part, such as a prism consisting of synthetic diamond and capable of carrying out an ATR spectroscopic analysis of a sample to be measured, which is deposited on an object in a place in bad environment, a structure or clothes, by merely bringing the prism into pressure contact with these objects, and a sample holding slide plate, which consists of synthetic diamond and has a long useful life, for an infrared microscope; and a measuring instrument using this prism. Since a total reflection (ATR) prism (14) of synthetic diamond the crystals of which have a nitrogen content of not more than 3 ppm and a boron content of not more than 3 ppm, optical mirrors (12, 17), lenses (13, 16) or fibers are used, a total reflection (ATR) spectroscopic analysis of a sample is carried out by bringing the prism into direct pressure contact with the sample (15) without using a holder.
    • 一种红外光学部件,例如由合成金刚石组成的棱镜,能够进行待测样品的ATR光谱分析,其沉积在恶劣环境中的物体上,结构或衣服上,仅通过 棱镜与这些物体进行压力接触,并且用于红外显微镜的样品保持滑动板,其由合成金刚石组成并且具有长的使用寿命; 以及使用该棱镜的测量仪器。 由于合成金刚石的全反射(ATR)棱镜(14)的晶体具有不大于3ppm的氮含量和不大于3ppm的硼含量,所以光学镜(12,17),透镜(13) ,16)或纤维,通过使棱镜与样品(15)直接压力接触而不使用保持器来进行样品的全反射(ATR)光谱分析。
