Donuts are used in the colour frame slot of an ellipsoidal reflector spotlight to sharpen gobo projections. Similar to the way the human eye sharpens focus when it squints, 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.

- Selecon Pacific Ellipsoidals (19-50 Degree)
- Strand SL
- Shakespeare
The ETC Source Four Zoom Compatible Donut is also suitable for use with:
