Christie 118-100112-xx Zoom Standard Throw Lens for 17 Compatible Models

Christie OEM Lens 118-100112-xx Zoom is an OEM optical accessory for Christie professional projectors. It is a standard-throw lens (Standard Throw) with a throw ratio of 1.50-2.00:1. The official model compatibility list covers 17 models; before installation, simply verify the projector model and panel size—no need to make do with an adapter ring. The value of an OEM lens lies not in the extra figures it adds to a specification sheet, but in the fact that it is calibrated at the factory to the optical path and mount of that projector series: once installed, the image circle, edge illumination, and focusing travel are all at their design values, eliminating the need to use keystone correction to compensate for image quality.

I. Lens Specifications

The above specifications are subject to Christie’s official specifications. For mechanical dimensions, flange distance, and mount type not shown in the specification table, please contact us with the projector model for verification. Ordering solely on the basis of a similar model carries the risk that the lens will not fit.

II. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This OEM lens is a zoom lens (1.50-2.00:1), so each image size corresponds to a range of installation distances, and the lens can focus at any position within that range.

The distances above are clear distances from the front surface of the lens to the screen and do not include space behind the projector for heat dissipation and cable connections. They are calculated for a 16:10 image; actual distances should be verified on site and in accordance with Christie’s manual.

Image quality differs at the two ends of the zoom range: near the short-throw end, the image is brighter and the edges are slightly softer; near the long-throw end, the edges are sharper and brightness decreases slightly. Where the venue permits, the middle of the range is recommended. After installation, first find the sharpest position using the focus ring, then fine-tune the lens shift.

III. Compatible Models (17 Models)

The table below is taken from Christie’s official model compatibility list. Brightness and resolution have been added from the model database; entries that could not be retrieved are shown as “—”, with no values inferred.

To verify whether a model not on the list is compatible, please send us photos of the projector nameplate and the existing lens—platforms from the same generation often share a mount, but placing an order based on a similar model name is not worth the risk.

Throw Ratio by Projector Series

The rated throw ratio of the same 118-100112-xx Zoom varies by projector series. When selecting a lens, use the value corresponding to the series of the actual projector.

IV. Three Checks Before Replacement

• Confirm the projector imaging chip and resolution.OEM lenses are designed for a specific panel size. If the panel specifications differ, the image circle will not cover the full panel, resulting in vignetting or light loss at the edges.
• Calculate the installation distance first.This lens has a rated throw ratio of 1.50-2.00:1; use the table in Section 2 to calculate the distance for your venue’s screen size. Fixed-focus lenses offer no adjustment margin, and zoom lenses still require 10–20 cm of allowance at both ends.
• Verify the mount and locking mechanism.The OEM lens is calibrated to the mount of that projector series, and you must hear it lock into place after installation. A skewed image or soft edges usually indicate that the lens is not fully locked, rather than a problem with the lens itself.

If you are unsure, take one photo of the projector nameplate and one of the current lens nameplate, then send them to us. Verification against the actual equipment is the most reliable approach.
