美国PHOTO RESEARCH公司最近推出了世界上最小的便携式分光光度计——PR650分光光度计。该仪器采用全息衍射光栅分光,条形CCD接受,并将数据处理与测光系统合为一体。由于其高度集成化、体积很小、且价格低廉,故成为当今世界上光辐射和颜色仪器的最新潮流。仪器适用范围广,可测亮度、照度、色坐标、色温透射率、反射率、辐射度、辐照度、色散L“U”“V”、L PHOTO RESEARCH, USA, recently introduced the PR650 spectrophotometer, the world’s smallest portable spectrophotometer. The instrument uses holographic diffraction grating spectroscopy, strip CCD accepted, and the data processing and metering system integration. Due to its high degree of integration, small size, and low price, it becomes the latest trend of optical radiation and color instruments in the world. Instrument wide range of applications, measurable brightness, illumination, color coordinates, color temperature transmittance, reflectivity, irradiance, irradiance, dispersion L “U” “V”, L
