Donut for a Selecon Pacific Zoom Spot

7 ⅜” x 7 ⅜”

187 x 187 mm

Donuts are used in the color frame slot of an ellipsoidal reflector spotlight to sharpen gobo projections. A donut reduces the aperture and sharpens the output of the fixture. There is some reduction in brightness to achieve this increase in sharpness but this is often a tradeoff that designers are willing to make.
