Christie Lens 3.89-5.431 (UHC 4K) - 163-122106-01

Product Overview

The Christie 163-122106-01 is an ultra-high-contrast (UHC) ILS4 zoom projection lens with a 3.89-5.43:1 throw ratio, designed for Christie 4K 3DLP projector platforms. It serves long-throw installations where image contrast is a priority, such as premium venues and dark-room environments. As an ILS4 lens, it supports motorized operation with automatic recognition on compatible projectors.

Product Description

This UHC zoom lens pairs a long 3.89-5.43:1 throw ratio with optics engineered for maximum contrast on Christie's ILS4-compatible 4K 3DLP projectors. The projection distance works out to roughly 3.89 to 5.43 times the projected image width, suiting deep auditoriums, projection booths, and balcony positions. The ultra-high-contrast design preserves black-level performance and image depth, which matters most in controlled-light environments such as theaters, visualization rooms, and premium screening spaces. Within the Intelligent Lens System family, the lens is recognized automatically when installed, and motorized zoom and focus positions can be recalled with repeatable accuracy. Confirm compatibility against your specific projector part number before ordering; our team can verify fit.
