Gobo frame

A gobo in a gobo holder, which goes in a stage lighting instrument. The discolored portion is oxidation of the stainless steel caused by the high temperature of the lamp, but

the gobo is still usable.

A gobo is a template or pattern cut into a circular plate used to create patterns of projected light. The name may be derived from go between, or from Goes Before Optics. Go between refers to its position between the lamp and the lens. Another origin may be: Graphical optical blackout.
