The orientations shown in Figure 11 are correct in most cases, but consult your Martin dealer or gobo
supplier if you are in any doubt about the orientation of a specific gobo type.
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. The coated gobos in the MAC 575 Krypton
are factory-installed in this position. However, if there is an unusually high risk of heat
damage on a custom coated gobo, the first priority is normally to ensure that more reflective
sides face towards the lamp. If in doubt, install coated gobos with the more reflective side
towards the lamp, or consult your Martin dealer or gobo supplier.
More reflective side towards lamp
To minimize the risk of gobo overheating
and damage, turn the more reflective side of
a coated gobo towards the lamp.
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.
Smooth side towards lamp
Textured glass gobos in the MAC 575 Krypton give the best focus results with the smooth
side towards the lamp. If in doubt, consult your Martin dealer or gobo supplier.
