Christie 118-100116-01 Zoom Long-Throw Lens: Compatibility with 30 Models

Christie Genuine Lens 118-100116-01 Zoom is a genuine optical accessory for Christie professional projectors. It is a long-throw (Long Throw) lens with a throw ratio of 7.50-11.20:1. The official model compatibility list covers 30 projector models. Before installation, simply verify the projector model and panel size; there is no need to improvise with an adapter ring. The value of a genuine 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 lens mount of that model 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 subject to the manufacturer's official specifications. For mechanical dimensions, flange distance, and mount type not listed in the specification table, please provide your projector model so we can verify them. Ordering solely based on a similar model carries the risk that the lens will not fit.

II. Installation Distance Based on Throw Ratio

The throw ratio is the installation distance divided by the image width. This genuine lens is a zoom lens (7.50-11.20:1), so each image size corresponds to a range of installation distances, and the lens can focus throughout that range.

The distances above are the clear distances from the front surface of the lens to the screen and do not allow for rear cooling clearance or cable connections on the projector. These figures are based on a 16:10 image; actual distances should be verified through on-site measurements and in accordance with the manufacturer's official manual.

Image quality differs at the two zoom extremes: the image is brighter and the edges are slightly softer near the short end, while the edges are sharper and brightness is slightly lower near the long end. If the venue allows, use the middle of the range. After installation, find the sharpest position on the focus ring, then fine-tune the lens shift.

III. Compatible Projector Models (30 Models)

The following table is taken from the official model compatibility list. Brightness and resolution have been populated from the model database; where the data is unavailable, “—” is shown, and no assumptions are made.

For models not on the list, send us photos of the projector nameplate and the existing lens so we can verify compatibility. Platforms of the same generation often share the same mount, but ordering based solely on a similar model name is not worth the risk.

Throw Ratios by Model Series

The rated throw ratio of the same 118-100116-01 Zoom lens varies among the model series listed below, so use the ratio for the series of the actual projector when selecting a lens.

IV. Three Checks Before Replacement

• Confirm the projector imaging chip and resolution. Genuine lenses are 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.
• Calculate the installation distance first. This lens has a rated throw ratio of 7.50-11.20:1. Use the table in Section II to match the dimensions of your installation site. A fixed-focus lens offers no adjustment margin, and even a zoom lens requires an additional 10–20 cm at both ends of the range.
• Check the mount and locking mechanism. Genuine lenses are calibrated to the mounts used by that model series, and the lens must audibly 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 photo of the projector nameplate and one of the existing lens nameplate, then send them to us. Verification against the actual hardware is the safest approach.
