This Strand Lighting Pattern Holder for M Size Steel Gobos for Acclaim Zoomspots is used to hold a gobo (a disc placed in the optical path of a lighting fixture used to project a pattern) for the Acclaim and Acclaim Axial 12 -18 ° and 24 - 44° Zoomspots. This fully hand-tooled pattern holder is designed so that the image can be aligned on stage by just rotating the holder in the light's gobo / iris slot without taking the holder in and out to realign the pattern. This holder is specifically designed for steel gobos (there are also glass gobos) in M size (66 mm outer dimension).
Spring clamp secures the pattern with an equal pressure around its complete diameter. This is important because it helps ensure the best in focus projection across the pattern image. Other holders grab the pattern at 3 or so points and as the pattern expands and contracts with the heat they distort and buckle. As a result the image can never be evenly in focus across the beam.
The image can be aligned on stage as required by simply rotating the holder in the gate. No need to take the holder in and out to realign the pattern in the holder and no burnt fingers in the process.
