Christie 140-159106-01 Short Zoom Lens: 6-Model Compatibility Guide

Christie Original Lens 140-159106-01 Short Zoom is an OEM optical accessory for Christie professional projectors. It is a standard-throw lens (Standard Throw) with a throw ratio of 0.90-1.30:1. The OEM compatibility list covers 6 models, so simply verify the projector model and panel size before installation—no adapter rings are needed. The value of an OEM lens lies not in the extra figures on a specification sheet, but in its factory calibration to the optical path and mount of that projector series. Once installed, the image circle, edge illumination, and focus travel all meet the design specifications, eliminating the need to use keystone correction to compensate for image quality.

1. Lens Specifications

The above specifications are subject to the OEM specifications. For mechanical dimensions, flange distance, and mount type not shown in the specification table, please contact us with the projector model. Ordering solely because the model names are similar carries the risk that the lens will not fit.

2. Converting Throw Ratio into Installation Distance

The throw ratio is the ratio of the installation distance to the image width. This OEM lens has a zoom range of 0.90-1.30:1, so each image size corresponds to a range of installation distances. The lens can focus at any position within that range.

These figures represent the clear distance from the front surface of the lens to the screen and do not account for ventilation or cable-management space behind the projector. They are calculated for a 16:10 aspect ratio; actual distances are subject to on-site measurements and the OEM manual.

Image quality varies at the two ends of the zoom range. Toward the shorter-throw end, the image is brighter and the edges are slightly softer; toward the longer-throw end, the edges are sharper and brightness decreases slightly. Where space permits, use the middle of the range. After installation, find the sharpest position on the focus ring first, then fine-tune the lens shift.

3. Compatible Models (6 units)

The following table is taken from the OEM compatibility list. Brightness and resolution are populated from the model database; unavailable data is marked “—” without speculation.

To determine whether a model outside the list is compatible, send us photographs of the projector nameplate and the existing lens. Platforms of the same generation often share the same mount, but ordering based only on a similar model name is not worth the risk.

Throw Ratios by Model Series

The nominal throw ratio of the same 140-159106-01 Short Zoom lens varies depending on the projector series. Select the appropriate value based on the series of the actual projector.

4. Three Checks Before Replacement

• Confirm the projector imaging chip and resolution.OEM lenses are designed for specific panel sizes. If the panel specifications differ, the image circle cannot provide full coverage, resulting in vignetting or edge light loss after installation.
• Calculate the installation distance first.This lens has a rated throw ratio of 0.90-1.30:1. Use the table in Section 2 to match the dimensions of your installation site. Fixed-focus lenses provide no adjustment margin, and zoom lenses should also leave 10–20 cm of margin at both ends.
• Verify the mount and locking mechanism.OEM lenses are calibrated to the mount of the corresponding projector series. You must hear the lens click into the locked position after installation. A skewed image or soft edges are usually caused by incomplete locking rather than a problem with the lens itself.

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