NEW City Theatrical 6" Ellipsoidal/ S4 Zoom Donut (Pkg of 15)

Package of 15. 

The NEW City Theatrical 6" Ellipsoidal/ S4 Zoom Donut is designed to fit in the color frame slot of an ellipsoidal reflector spotlight to help sharpen gobo and template projections. Similar to the way the human eye sharpens focus when it squints, a donut reduces the aperture and tightens the beam, helping bring templates into perfect sharpness. There is some reduction in brightness to achieve this increase in sharpness, but this is often a tradeoff that designers are willing to make.

How It Improves Gobo and Template Sharpness

By reducing the effective opening at the front of the fixture, the donut can minimize stray light and soften edge artifacts, making projected patterns read cleaner on scenery, cyc, or architectural surfaces. It is a simple, fast add-on for situations where projection crispness matters more than maximum output.

Construction and Dimensions

Each donut is fabricated from light gauge steel with a durable black powdercoat finish for low reflectivity and reliable handling in production environments. Dimensions are A- 7 1/2", B- 7 1/2", C- 3".
