Optical configuration 21
Gobos
Gobo wheel 1 provides 6 rotating gobos; gobo wheel 2 provides 9 static gobos. The standard gobo
configuration is shown in Figure 10 on page 21.
All gobos are interchangeable with the following limitations:
• On wheel 1, the gobo retention spring works with gobos up to 3 mm in thickness. Thicker gobos can be
glued to the holder with a UV adhesive or Loctite 330 Multibond with Activator.
• Glass gobos in the rotating gobo wheel are generally glued to the goboholders and must therefore be
changed as a unit.
• The maximum thickness for gobos on wheel 2 is 1.1 mm (0.043 inches).
Custom gobos
Martin can provide many additional gobos for the MAC 575 Krypton. Gobos are interchangeable between
MAC 500, MAC 550, MAC 575 and MAC 700 fixtures. For more information, please visit the Martin website
at www.martin.com.
For optimum performance and gobo life, custom glass gobos should be made with the artwork reversed on
the coated side and used with the coated side facing away from the lamp.
While glass gobos are generally the most durable, satisfactory results can be obtained at less expense with
aluminum gobos. Custom stainless steel gobos can also be used, however they can warp, losing
sharpness, in a matter of hours. The useful life will depend on the gobo pattern and the projection cycle.
Consult your gobo supplier for more information.
For best results, custom gobos should meet the specifications listed on page 43.
