Christie 140-111104-XX Zoom Long-Throw Lens: Compatible with 25 Models

Christie Factory-Original Lens 140-111104-XX Zoom is a factory-original optical accessory for Christie professional projectors. It is a Long Throw lens with a throw ratio of 2.00-4.00:1. The official compatibility list covers 25 models. Before installation, simply verify the projector model and panel size; there is no need to make do with adapter rings. The value of a factory-original lens lies not in the extra rows of specifications, but in the fact that it is calibrated at the factory to the optical path and mount of the corresponding projector series. Once installed, the image circle, edge illumination, and focus travel all meet their design values, so there is no need to use keystone correction to compensate for image quality.

I. Lens Specifications

The above specifications are based on the manufacturer's official specifications. Mechanical dimensions, flange distance, and mount type are not listed in the table; please contact us with your projector model to verify them. Ordering based solely on a similar model carries the risk that the lens will not fit.

II. Converting Throw Ratio into Installation Distance

The throw ratio is the ratio of the installation distance to the image width. This factory-original lens is a zoom lens (2.00-4.00:1), so a given image size corresponds to a range of installation distances; it can focus at any position within that range.

These distances represent the clear measurement from the front of the lens to the screen and do not include space behind the projector for cooling and cabling. The figures are calculated for a 16:10 image; in practice, follow on-site measurements and the manufacturer's manual.

Image quality differs at the two ends of the zoom range: near the close end, the image is brighter and the edges are slightly softer; near the far end, the edges are sharper and brightness decreases slightly. If the venue allows, use the middle of the range; after installation, turn the focus ring to the sharpest setting, then fine-tune the lens shift.

III. Compatible Models (25 Models)

The following table is taken from the official compatibility list. Brightness and resolution values have been populated from the model database; unavailable values are shown as “—” and have not been inferred.

For models not on the list, please send us the projector nameplate and a photo of the current lens so we can verify compatibility. Platforms of the same generation often share lens mounts, but the risk of ordering based on a similar model is not worth taking.

Throw Ratios by Model Series

The nominal throw ratio of the same 140-111104-XX Zoom lens varies across the series listed below, so use the value for the series of the actual projector when selecting.

IV. Three Checks Before Replacement

• Confirm the projector chip and resolution. The factory-original lens is designed for a specific panel size; when the panel specifications differ, the image circle cannot cover the full panel, resulting in vignetting or edge light loss after installation.
• Calculate the installation distance first. This lens has a nominal throw ratio of 2.00-4.00:1. Use the table in Section II to calculate the distance for your venue. A fixed-focus lens offers no adjustment margin, and a zoom lens should also allow 10–20 cm at both ends.
• Verify the mount and locking mechanism. The factory-original lens is calibrated to the mount of the corresponding projector series. After installation, you must hear it click into the locked position. A skewed image or soft edges usually indicate that the lock is not fully engaged, 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 and send them to us. Verification against the actual items is the safest approach.
