In a matter of seconds, using a fisheye-lens camera, the system measures the high-resolution light intensity distribution of the lamp or luminaire under test. The system also automatically calculates the spatial correction factor for the luminous flux measurement.
The fisheye camera method reduces measurement uncertainty in luminous flux measurements with integrating spheres. It is especially useful when measuring LED light sources and other lighting products with non-uniform angular distributions.
The software handles all the necessary image capturing, processing and data analysis automatically. To obtain the luminous intensity distribution, all you need to do is switch the light source on.
The software supports exporting and importing data to and from different file formats such as IES LM-63 (.ies) and EULUMDAT (.ldt), making it easy to integrate fisheye camera method to your existing system.
