specbos 1201 is one of the smallest VIS spectroradiometers available worldwide (download datasheet). Its easy-to-use software has the full complement of radiometric and colorimetric functions requisite for research, diagnostic, and quality control applications. Several special calculations and features are implemented in the software JETI LiVal e.g. the calculation of RGB, PAR and circadian values, pass/ fail functions and a LED Ranker (Ranking of LED's and other light sources; see applications).
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.
