Christie 144-131106-01 Zoom Long-Throw Lens for 5 Projector Models

Christie Genuine Lens 144-131106-01 Zoom is a factory-supplied optical accessory for Christie engineering projectors. It is a long-throw (Long Throw) lens with a throw ratio of 1.95-3.26:1. The manufacturer's compatibility list covers 5 models; before installation, simply verify the projector model and panel size—there is no need to make do with an adapter ring. The value of a genuine lens lies not in the extra figures it adds to the specification sheet, but in the fact that it is calibrated at the factory to the optical path and mount of the relevant projector series. Once installed, the image circle, edge illumination, and focusing travel all meet the design values, with no need to use keystone correction to compensate for image quality.

I. Lens Specifications

The above specifications are subject to the manufacturer's official specifications. For mechanical dimensions, flange distance, and mount type not shown in the specification table, please contact us with the projector model so we can verify them. Ordering based solely on 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 genuine lens is a zoom lens (1.95-3.26:1), so each image size corresponds to a range of installation distances. The lens can focus anywhere within that range.

The above figures show the clear distance from the front of the lens to the screen and do not include space for cooling or cable connections at the rear of the projector. They are calculated for a 16:10 image; for actual installation, rely on on-site measurements and the manufacturer's manual.

Image quality differs at the two ends of the zoom range: toward the close end, the image is brighter and the edges slightly softer; toward the far end, the edges are sharper and brightness decreases slightly. If venue conditions allow, aim for the middle of the range. After installation, first find the sharpest position using the focus ring, then fine-tune the lens shift.

III. Compatible Models (5 Projectors)

The table below is taken from the manufacturer's compatibility list. Brightness and resolution are populated from the model database; where unavailable, they are marked “—” and have not been estimated.

For compatibility with models not on the list, please send us photos of the projector nameplate and the existing lens for verification. Projector platforms from the same generation often share the same mount, but it is not worth the risk of ordering based solely on a similar model designation.

Throw Ratios by Projector Series

The same 144-131106-01 Zoom has different rated throw ratios across the series listed below. When selecting a lens, use the value corresponding to the series of the projector in question.

IV. Three Checks Before Replacement

• Check the projector imaging chip and resolution. The genuine lens is designed for a specific panel size. If the panel specifications differ, the image circle cannot cover the full image, resulting in vignetting or light loss at the edges after installation.
• Calculate the installation distance first. This lens has a rated throw ratio of 1.95-3.26:1; use the table in Section 2 to calculate the distance for your venue. A fixed lens offers no adjustment margin; with a zoom lens, allow 10–20 cm of margin at both ends.
• Verify the mount and locking mechanism. The genuine lens is calibrated to the mount of that projector series, and you must hear the lock engage fully after installation. A skewed image or soft edges are usually caused by an incompletely locked lens, not by a fault in the lens itself.

If you are unsure, send us one photo of the projector nameplate and one of the nameplate on the existing lens. Verification against the actual hardware is the most reliable approach.
