Christie 3.89-5.43:1 ILS High-Brightness Zoom Lens - 144-108100-03

Product Overview

The Christie 144-108100-03 is a high-brightness ILS4 zoom projection lens with a 3.89-5.43:1 throw ratio. It is designed for long-throw installations where the projector must sit well back from the screen. As an ILS4 (Intelligent Lens System) lens, it supports motorized, repeatable recall of lens position settings on compatible Christie 3DLP projectors.

Product Description

This long-zoom lens extends the placement flexibility of Christie's ILS4-compatible 3DLP projector platforms. The 3.89-5.43:1 throw ratio means the projection distance is roughly 3.89 to 5.43 times the projected image width, making the lens appropriate for deep rooms, balcony projection booths, and large venues where the projector cannot be placed close to the screen. The high-brightness optical design prioritizes light throughput, preserving as much of the projector's lumen output as possible across the zoom range. Because it is part of the Intelligent Lens System family, the lens is automatically recognized when installed and supports motorized zoom and focus with accurate position recall. Confirm compatibility with your specific Christie projector model before ordering; our team can verify fit against your chassis part number.
