Glass gobos use coloured glass to get the picture/shape/pattern you want, they work in a similar way to metal gobos except where you do not want light projected it is coloured black. Very relistic pictures can be put onto glass gobos to create wonderful projections. The projection can be further enhanced or ruined by the use of [[wp>dichroic]] filters. | Glass gobos use coloured glass to get the picture/shape/pattern you want, they work in a similar way to metal gobos except where you do not want light projected it is coloured black.

Gobos are of different size, both physical and projection, and fixing methods if replaceable, are dependent on the fixture and/or manufacturer of the fixture. | Gobos are of different size, both physical and projection, and fixing methods if replaceable, are dependent on the fixture and/or manufacturer of the fixture. |

Gobos may or may not be replacable, if they are you can get your own gobos designed/manufactured. If not you might be able to get the whole wheel cut (see the first picture below). | Gobos may or may not be replaceable, if they are you can get your own gobos designed/manufactured.

Metal gobos are cheaper to create than glass gobos because it normally just involves laser cutting the required shape out of the thin stainless steel. | Metal gobos are cheaper to create than glass gobos because it normally just involves laser cutting the required shape out of the thin stainless steel. |
Gobos are either static or can be [[Gobo rotation|Rotated]] and or [[Gobo Shake|Shaken]] and or [[Indexable Gobos|Indexable]]. | Gobos are either static or can be [[Gobo rotation|Rotated]] and or [[Gobo Shake|Shaken]] and or [[Indexable Gobos|Indexable]]. |

If you want to get your own static replacable gobo, you will need to check the orientation of the replacable gobo to ensure you get it manufactured correctly so when fitted it displays as you want to see it. Remember there are multitudes of ways a fixture can be mounted. What is meant by this for example is a gobo that has a word on it and projects correctly when a scanner is hanging down will mean that if the scanner is mounted the other way around the gobo will be upside down. Some fixtures do not allow fixing the replaceable gobo in any position as they use a key slot. | If you want to get your own static replaceable gobo, you will need to check the orientation of the replacable gobo to ensure you get it manufactured correctly so when fitted it displays as you want to see it.
