Christie ILS1 1.28-1.87:1 UHC Zoom Lens for M 4K25-RGB - 163-165103-01

Product Overview

The Christie 163-165103-01 is an ILS1 ultra-high-contrast (UHC) zoom projection lens with a 1.28-1.87:1 throw ratio, specified for the Christie M 4K25-RGB 3DLP projector. The UHC optical design preserves contrast and black-level performance on the M 4K RGB pure laser platform. ILS1 format provides Intelligent Lens System recognition and motorized, repeatable lens positioning.

Product Description

This lens pairs Christie's M 4K25-RGB projector with a standard-throw zoom range suited to a wide variety of venue geometries. At 1.28-1.87:1, the projector is positioned roughly 1.28 to 1.87 times the image width from the screen, fitting typical auditorium, event, and installation distances without extreme optics. The ultra-high-contrast design maintains image depth on the RGB pure laser light engine, which is particularly valuable in controlled-light environments where black-level performance is visible. As part of the Intelligent Lens System family, the lens is recognized on installation and supports motorized zoom and focus with accurate position recall, simplifying setup and lens swaps in rental workflows. Verify fit against your specific projector configuration before ordering; our team can confirm compatibility.
