Luminance Measurement System luca

Luminance Measurement System luca

opsira’s spatially resolving luminance measurement system luca is used for development as well as for quality control of optical systems.

luca records data that can be used for the simulation and the development of optical systems. Illuminances and luminous intensity distributions can be recorded and analyzed with our luca’lux system add-on. luca provides a wide range of application because of its nearly six orders of dynamic range. The system very quickly measures objects of very low luminance (only a few cd/m2) as well as extremely powerful light sources such as high-pressure discharge lamps. The system cameras operate in a 12-Bit mode (software supported up to 20-Bit) and their detectors can be cooled if necessary while their optics contains precision lenses from LINOS/Rodenstock. Our powerful control and evaluation software, luca’tool, is available for all metrology systems.

In addition to luminance measurements, our luca’color system measures the spatially resolved color distribution; however, it captures the spatially resolved planar image in one shot and not in a selective way like a standard-colorimeter. The system includes an integrated filter wheel with ten filter positions that allows a direct measurement of color values according to CIE. Chromaticity coordinates and color difference values are delivered directly by user-specified evaluation labels.
Additional multiple weighting functions are possible because of the ten total filter positions.
