Christie 4.1 to 6.9:1 ILS Zoom Lens - 118-100115-03

Product Overview

The Christie 118-100115-03 is a long-throw ILS zoom lens with a 4.1 to 6.9:1 throw ratio for Christie M Series-mount 3DLP projectors. Its 1.68x zoom range provides power zoom and power focus for remote adjustment, so the image can be sized and sharpened from the operator position. As an ILS (Intelligent Lens System) lens, it is automatically recognized and calibrated by the projector on installation. This is the optic for the longest projection distances in the M Series lens suite.

Product Description

Some venues simply cannot put the projector close to the screen: arenas with rear projection booths, large auditoriums with back-wall positions, and architectural projection across streets or plazas. The 4.1–6.9:1 ratio places the projector four to nearly seven times the image width from the screen, keeping it out of sightlines and accessible spaces while still filling large surfaces. The 1.68x motorized zoom lets operators fine-tune image size remotely, and power focus brings the image sharp without a ladder trip to the projector. Because it shares the M Series ILS mount, the lens interchanges with the rest of the suite across compatible Christie 3DLP projectors, and stored lens positions recall repeatably thanks to the ILS architecture. For rental inventories, it rounds out the lens kit for shows where the projection position is dictated by the venue, not the designer.
