The measuring cameras of the product family luca enable the high-resolution measurement of luminance and radiance distributions.
luca analyzes the spatially resolved luminance in a fast and easy way, whether you measure displays, control elements or luminaires.
The comfortable control and evaluation software offers a variety of evaluation functions.
luca is based on high-quality CMOS-matrix cameras and, in HighDyn mode, provides up to 5 decades of dynamics within one measurement – at an outstanding signal-to-noise ratio.
The system add-on luca'color allows measurements of up to 10 different spectral weighting functions. Thus, besides the luminance photometer measurement, the spatially resolved measurement of the color distribution according to CIE 1931 is possible. Furthermore, in combination with one of the opsira goniophotometers, polychromatic ray data for the use in optics simulation can be generated. Further spectral weightings can easily be realized.
A great number of different measuring lenses facilitate a high flexibility in the size of the measuring lenses.
luca’remote, the powerful TCP/IP interface is available for the integration of luca into automated control processes, such as end-of-line controls.
