A pre-cut, etched pattern fabricated from metal or glass that fits in the focal plane of a lighting instrument to form projected light into a shape (logo, graphic or even scenery). Templates can form light images on ceilings and walls. The pattern or template can be used in a projection type spotlight, to project decorative patterns on the walls. The "Bat" image from "Batman" is an example.
image or pattern placed in the gate of a profile spot to project an image. Usually made of etched stainless steel or brass in a process similar to that used when making PCBs, glass and mesh tone varieties are available. Glass gobos can use dichroic filters to provide coloured images.
Is an etched plate, usually metal, put in front of a spotlight so that it casts a pattern on stage. Gobos can be used in all kinds of neat ways, for example, to imitate the effect of light filtered through foliage or to create the effect of a neon sign.
A sheet with cutouts on it that creates interesting shadows when placed in front of your light source. Imagine a metal sheet with squares cut into it resembling those of a Belgian waffle. If you angle your light at 45 degrees to a background and put this piece of metal in front of it, you'll get super-funky geometric effects. You can make your own and they can be quite fun to play with
A thin metal plate etched to produce a design which can then be projected by a profile spotlight (E.g. Foliage, Windows). The image can be used soft focus to add texture, rather than a defined image. A number of composite gobos in different coloured lanterns can, with careful focusing, produce a coloured image (e.g. a stained glass window). Greater detail can be achieved using a glass gobo. The original use of the word GOBO came from the early days of Hollywood. When the Director of Photography wanted daylight excluded from some area of the set, he'd say "GO BlackOut". Loads of people would run around putting black material between the sun and the set. It eventually evolved into other stuff that goes in front of lights and now most commonly (in the UK at least), refers to patterns in profiles. In the US TV/Film industry, a Gobo is a piece of material used to mask or block light and a Cookie (short for Cucaloris(from the Greek kukaloris
Inserted into the focal plane of a profile luminaire, these patterns allow projection of images.
a form of slide usually made of stainless steel or brass into which an image is cut
a mask is used to create patterns or shapes with light on the stage
an image that is projected onto any surface
a piece of material (normally aluminium plate) with a pattern cut in it to let light through
a piece of (usually) metal that will cast a shadow when light is projected through it
a slide, usually made of metal that slips in front of a projector
a stencil, which filters the light and creates an image
a thin mask that is placed in the gate of a profile spot that produces a light beam onto the wall
a thin, metal (now often glass) plate, with a shape cut out in the center
A piece of metal or glass, which fits into the gate of a profile spot and projects a pattern onto the set. Gobos can be very complex. They are first fitted into a gobo holder. Holders vary in size (each type of lantern requires a different size), although the gobos themselves are of a standard size. Most basic gobos are made of metal but very complex patterns can be created on glass gobos. Also called Template.
A special pattern made of metal or glass that can be installed into the aperture of a light source to project a pattern.
A thin disc of stainless steel with a pattern of holes which is inserted in the gate of a profile spot to project the pattern onto the stage.
Also called a pattern, template, or cookie, a gobo is commonly an etched steel cut-out placed at the gate of an ERS which produces a pattern of light and shadow in the beam of light. Patterns are commercially available from theatrical lighting dealers or can be made by hand using a number of different processes. Many automated fixtures employ a variety of gobos and gobo effects. These include rotatable gobos, gobo combinations, glass colored gobos, or even sophisticated imaging systems which combine dichroic color effects with patterns or custom designs or artwork.

A thin metal template with a cutout design which can be projected when used in the optic gate of a profile lantern.
A pattern or breakup (or any opaque unit) placed in a spot luminaire, designed to cast a design onto a surface; a "go-between." Or, according to Hollywood tradition, a "GoBlackOut." Also called a Cookie (Cucaloris).
A gobo, also called template or pattern, is a thin circular plate with holes cut in it to create patterns of projected light. The name may be derived from go between, or from Goes Before Optics. Go between refers to the its position between the lamp and the lens.
