The MAC 500/E has 5 rotating positions for glass or metal gobos, 9 static positions for metal gobos, and 9 positions for interchangeable dichroic glass color filters in special holders. This section describes how to replace these items.

For best results, MAC 500/E gobos should meet the following specifications.

G l a s s g o b o s

•

Coating:

dichroic or enhanced aluminum

•

Material:

high temperature, Borofloat or better

•

Thickness:

......... 1.1- 4.0 mm

•

Outside diameter:

27.9 + 0 /- 0.3 mm

•

Maximum image diameter:

..... 23 mm

Glass gobos should be made with the artwork reversed on the coated side. This orientation gives the best focus but is not critical. We do not recommend using chrome-coated glass gobos in the MAC 500/E. They absorb more heat than enhanced aluminum gobos and are likely to break or oxidize. If used, their lifetime can be extended somewhat by inserting the gobos with the coated side towards the lamp.

M e t a l g o b o s

•

Material:

............... aluminum

•

Thickness:

................. 0.5 mm

•

Outside diameter:

27.9 + 0 /- 0.3 mm

•

Maximum image diameter:

..... 23 mm

*Steel metal gobos may give acceptable short term performance. Gobos less than 0.5 mm thick may need to be secured with a drop of high temperature silicone adhesive when used in the static positions.

For correct projection of text and images, the side with the true image must be installed facing in, towards the lamp. For best focus, the coated side of glass gobos should face out, away from the lamp. Textured glass gobos must be inserted with the smooth side facing in, towards the lamp.

Textured Gobos Coated Glass Gobos

Uncoated side towards lamp

When an object is held up to the uncoated side, there is a space between the object and its reflec- tion. The edge can be seen through the uncoated side.

Smooth side towards lamp

Coated side towards stage

When an object is held up to the coated side, there is no space between the object and its reflection. The edge cannot be seen through the coated side.
