The CORONA series designates our ring lights with special features. At the CORONA-series, the light surfaces can be angled at the factory between 0° and 45° to focus the light and obtain a light component similar to a dark field.
The IRIDA-180 is a multispectraldiffuse low-angle illumination with 5 separately controllable light colors. Furthermore, 4 sectors can be controlled separately.
