Each ILS4™ (Intelligent Lens System) lens automatically recognizes and calibrates the lens when it is installed. Stepper motor based encoding ensures that motor drift does not occur, providing accurate and repeatable recall of all lens offset, zoom and focus positions. Christie's 1.45-2.17:1 high brightness zoom lens is designed for installation with Christie projectors including Griffyn and Sapphire series, offering a medium-throw range suitable for a variety of projection applications requiring high brightness performance and flexible placement options in professional environments.
