-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.

 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.

-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.
