产品详情
specbos 1201 can be used for measurements in Irradiance mode as well as in Radiance mode with measuring diameters beginning from 4 mm. The special model specbos 1201 focus can measure diameters of 3 mm, 1 mm and 0.5 mm in radiance mode. Furthermore the model specbos 1201 flash is available. It measures pulsed sources, both single and continously flashed, in Irradiance mode.
