autoVimation offers highly efficient, easy-to-use polarization filters and diffusers for its innovative Meganova ring light used for installation in Orca, Shark and Megalodon protective camera enclosures.

The Meganova ring light is They are provided with eight high-power LEDs, placed directly behind the enclosure front window, eliminates the need for further external lighting. The ring light design is matched to the enclosure series cited above for efficient heat dissipation.

The Meganova ring light with polarizing filters eliminates light reflections into the camera lens

This allows for continuous operation at 200 % power and brightness under normal conditions. In standard vertical installations, coaxial orientation of light source and camera lens can cause light reflections on reflective surfaces and thus impair the inspection of metallic parts or paper packaging. The new Meganova polarizing filters solve this issue by means of two linear, crossed polarization filters, which completely eliminate light reflections into the camera lens and thus enable excellent imaging quality. The solution consists of a polarization ring placed over the ring of LEDs and a polarization disc for the central lens aperture, which eliminates the need for a polarizer on the lens.



The upper half of the image was taken with, the lower half without Meganova cross-polarizer

The ring and disc are simply attached to the lighting tube, then, the outer ring, which polarizes the LED light, is twisted against the inner disk until their polarization directions are offset by 90°. The newly available Meganova diffusion rings for homogenizing light distribution in the camera image are mounted analogously to the polarization ring. They are available in two versions with strong and weak diffusion at light transmission coefficients of 45 % and 80 % respectively.
