Christie 140-110103-XX Zoom Standard Throw Lens: 29 Compatible Projectors

Christie Original Lens 140-110103-XX Zoom is an original optical accessory for Christie engineering projectors, belonging to the standard throw range, with a throw ratio of 1.50-2.00:1. The factory compatibility list covers 29 models; before installation, simply check the chassis model and panel size — there is no need to improvise with adapter rings. The value of an original lens does not lie in a few extra rows of specifications, but in the fact that it is calibrated at the factory to the optical path and mount of that series: once fitted, the image circle, edge illumination, and focus travel are all at their design values, so there is no need to make up for image quality with keystone correction.

1. Lens Specifications

The above specifications are subject to the original manufacturer's data. For mechanical dimensions, flange distance, and mount type that are not shown in the specification table, please check with us using your chassis model; ordering directly on the basis of a similar model number 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 original lens is a zoom lens (1.50-2.00:1), so a given image size corresponds to a range of distances; as long as the installation falls within that range, the image can be focused.

These figures are the clear distance from the front of the lens to the screen, excluding the space needed for rear cooling and cable connections at the projector. They are calculated for a 16:10 image; in practice, on-site measurements and the original manufacturer's manual take precedence.

Image quality differs at the two ends of the zoom range: closer to the near end the image is brighter and the edges slightly softer; closer to the far end the edges are sharper and the brightness drops slightly. When the venue allows, aim for the middle of the range; after installation, first find the sharpest position on the focus ring, then fine-tune the lens shift.

3. Compatible Models (29 units)

The table below is taken from the original factory compatibility list; brightness and resolution are filled in from the model database, and models with no available data are marked with "—", with no speculation made.

To find out whether models outside the list can be used, send us photos of the chassis nameplate and the existing lens for verification — platforms of the same generation often share the same mount, but ordering on the basis of a similar model number is not worth the risk.

Throw Ratio by Model Series

The same 140-110103-XX Zoom fitted to the series below has different nominal throw ratios; choose the value according to the series your actual projector belongs to.

4. Three Things to Confirm Before Replacement

• Confirm the chassis panel and resolution.Original lenses are designed for a specific panel size; when the panel specifications differ, the image circle cannot cover the image, causing vignetting or edge light loss once fitted.
• Calculate the installation distance first.This lens has a nominal throw ratio of 1.50-2.00:1; apply the table in Section 2 to your own venue dimensions; a fixed-focus lens has no margin, and even a zoom lens needs 10–20 cm of allowance at both ends.
• Verify the mount and locking.Original lenses are calibrated to the mount of that series, and after fitting you must hear the lock engage; a skewed image or soft edges is usually caused by the lens not being fully locked, rather than by the lens itself.

If you are unsure, take one photo each of the chassis nameplate and the nameplate of the existing lens and send them to us; verification against the physical items is the safest approach.
