专利汇可以提供Photodiode array for spectro-photometer专利检索,专利查询,专利分析的服务。并且PURPOSE:To enable the alignment of wavelengths simply by electrically dividing the photodiode for wavelength calibration provided in the photodiode array by small gaps passing the center, and comparing electrical signals from the divided parts. CONSTITUTION:The calibrating photodiode 15 is provided at the central part of the photodiode array 14 wherein a plurality of photodiodes 2a-2d and 3a-3d are arranged at the upper and lower stages. The photodiode 15 is electrically divided into, e.g., four photodiodes 15a-15d, by the small gaps passing the center. The outputs from the divided parts are connected to displays 18a-18d. A bright circle 13, which is the image of a calibrating input slit 7c, is smaller than the calibrating photodiode 15, and the photodiodes 15a-15d are uniformly irradiated. The position of the photodiode array 14 is adjusted so that the output displays 18a-18d display the uniform outpus. In this constitution, accurate wavelength alignment can be performed by a simple operation, and components analysis by multiple wavelengths can be suitably performed.,下面是Photodiode array for spectro-photometer专利的具体信息内容。
