光电器件与一般的电子器件不同,其特点是它们与辐射的接收、转换及发射有直接的关系,即与光敏面或光发射屏有关。光电器件中的辐射接收器和辐射发射面在光谱特性方面一般都是选择性的,这是其主要的特征。因此,在生产验收与性能比较中都必须有一基准光源和接收器。在基准光源方面目前通用的为“A”光源的白炽灯,其色温T_色为2856K。在辐射接收 Optoelectronic devices and general electronic devices, which is characterized by their radiation with the conversion, and launch a direct relationship, that is, with the photosensitive surface or light emitting screen. Radiation receivers and radiation emitting surfaces in optoelectronic devices are generally selective in terms of spectral characteristics, which is their main feature. Therefore, in the production of acceptance and performance comparison must have a reference light source and receiver. The incandescent lamp currently used as a “A” light source in reference light sources has a color temperature of 2856K. Received at the radiation
