Each lens in the M Series suite of lenses is motorized and operates using Christie's Intelligent Lens System (ILS)™. The ILS automatically recognizes and calibrates a lens when it is installed. Stepper motor based encoding ensures that motor drift does not occur, as typically found with DC encoded motors, providing accurate and repeatable recall of all lens offset, zoom and focus positions.
When used with Christie M Series HD/WU products, this ILS fixed lens has a 0.37:1 throw ratio.
Please refer to the Christie Lens Calculator on this website or the downloadable PDF throw distance chart located in the resource tab of the Christie projector model to be used with this lens.
