Installing gobos
Most gobos must be installed facing in a certain direction in order to avoid heat damage. Follow the gobo
orientation guidelines given in Figure 3. Consult your Martin dealer or gobo supplier if you are in any doubt
about the orientation of a specific gobo type.
Coated Glass Gobos
Focus is easiest to maintain if all coated gobos in a fixture are installed with their coatings
as close as possible to the same plane of focus. However, the first priority is normally to
ensure that the more reflective side faces towards the LEDs.
More reflective side towards LEDs
To minimize the risk of gobo overheating
and damage, turn the more reflective side of
a coated gobo towards the LEDs.
Less reflective side away from LEDs
The less reflective side of a coated gobo will
absorb less heat if it faces away from the
LEDs.
To determine which side of a gobo is
coated, hold an object up to it. On the
uncoated side, there is a space between the
object and its reflection and the edge of the
gobo can be seen when looking through the
glass.
Textured Glass Gobos
Smooth side towards LEDs Textured side away from LEDs
Textured glass gobos in the Exterior 400 Image Projector give the best focus results with
the smooth side towards the LEDs. If in doubt, consult your Martin dealer or gobo supplier.

True image towards LEDs
Reversed image away from LEDs
Custom gobos must be designed so that the true image appears on the more reflective side
so that it faces the LEDs when installed.
