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. Our turnkey solution, Anglerfish, comes at a fraction of the operating and investment costs compared with traditional goniophotometers. For the science behind the method, have a look at  and .
Together with spatial uniformity map of the sphere, the fisheye camera method reduces measurement uncertainty in luminous flux measurements with integrating spheres. The spatial correction is especially important 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 various importing and exporting options, including file formats compatible IES LM-63 (.ies) and EULUMDAT (.ldt), making it easy to integrate fisheye camera method to your existing system.
