Abstract:
A polarizing hood including a first polarized filter with the center of the filter removed. Placed forward and in front of the first polarized filter is a second linear polarized filter substantially the size of the hole in the first polarized filter and is held in place by a clear lens. The polarization may be adjusted. In response to light collocated with an objective lens shined through the first polarizing filter, the light become polarized. The reflected polarized light returns through the second polarized filter, and full polarization is accomplished with respect to the viewing camera.
