Gobos in the MAC III Profile

The MAC III Profile uses specially-designed borosilicate 3.3 gobos with a heavy matted aluminum coating
that require particularly careful handling and storage.
The use of metal gobos in the MAC III Profile is not recommended.
Do not use gobos with dark coatings on any side, as these will absorb heat – either directly from the lamp or
reflected back from other gobos and optical components – and will not be durable.
Handling and storage
1. Store all gobos in a dust-free environment with approx. 50% humidity.
2. Always use clean gloves when handling gobos.
3. Avoid touching the other gobos when taking out a gobo from the rack: the sharp edge of one gobo can
scratch the others.
4. Clean the coated side of gobos with dust and oil-free compressed air only.
5. Clean the uncoated side of gobos with photographic quality lens-cleaner and optics cleaning tissues.
Use a repeated dabbing action rather than a rubbing action.
6. Avoid scratching coated and uncoated sides.
7. Never place a gobo with the coated side face-down on any surface.
8. Mount the gobo with the matted coating towards the lens.
