equipped both with Aluminum- and Glass gobos
(outside diameter 27 mm, image size 21 mm). When using customized Gobos
like company logos and writing the recommended image size is 18 mm. You
can use either Aluminum (thickness = 0.5 mm) or glass gobos (thickness = 1.1 -
3.0 mm).
There are two gobo wheels with rotating gobos, with all gobos being
interchangeable.
4.1.1 General remarks for changing gobos
All gobos or other optical effects have a dedicated mounting direction.
To prevent undesired damages and to optimize the optical performance
of your gobos, all gobos should be mounted with their reflecting side
towards the LED light source.
a) Aluminum gobos must be mounted with their unpainted side towards
the LED light source, and the black painted side towards the front
lens.
b) Glass gobos must be mounted with their reflecting, or coated side,
towards the LED light source.
To find out which is the coated side of a glass gobo, take a pencil
and place the point gently on the gobo. If you have touched the
coated side, there will be no distance between the pencil tip and its
reflection in the gobo. If you have touched the uncoated side, there
will be a small distance between the pencil tip and its reflection
Attention: Customized gobos like company logos, or those with
writing also need to be placed in the holder with the correct
orientation to ensure that the projected image reads correctly. Place
the side of the gobo which reads correctly towards the LED light
engine to ensure that it projects properly. Remember that the
reflective side of the gobo should also be towards the LED light
source, so please instruct the gobo manufacturer accordingly when
having customized gobos made.
c) Glass Gobos with a structured surface must be mounted with the
structured surface towards the LED light source and the flat side
