Christie 118-100116-xx Zoom Telephoto Lens for 20 Projector Models

Christie Original Lens 118-100116-xx Zoom is an original optical accessory for Christie professional projectors. It is a long-throw (Long Throw) lens with a throw ratio of 6.90-10.40:1. The official compatibility list covers 20 models. Before installation, simply verify the projector model and panel size; no adapter rings are needed. The value of an original lens lies not in the additional figures in the specification sheet, but in the fact that it is calibrated at the factory to the optical path and lens mount of that projector series. Once installed, the image circle, edge illumination, and focus travel are all at their design values, so there is no need to compensate for image quality with keystone correction.

I. Lens Specifications

Brand	Christie (Christie)
Lens Model	118-100116-xx Zoom
Throw Ratio	6.90-10.40:1
Product Type	Long Throw (Long Throw)
Compatible Models	20 Projector Models
Warranty	12 months; accidental damage can be handled through after-sales service, based on the date on the shipping invoice

These specifications are subject to the manufacturer's official specifications. Mechanical dimensions, flange distance, and mount type are not listed in the specification table. Please provide your projector model so we can verify them. Ordering solely because the model numbers are similar 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 original zoom lens (6.90-10.40:1) produces a range of distances for the same image size and can be focused anywhere within that range.

Image Size	Image Width	Required Installation Distance
100 inches	2.15 m	Approx. 14.84 – 22.36 m
120 inches	2.58 m	Approx. 17.80 – 26.83 m
150 inches	3.22 m	Approx. 22.25 – 33.54 m
200 inches	4.30 m	Approx. 29.67 – 44.72 m

The distances above represent the clear distance from the front of the lens to the screen and do not include clearance for ventilation or cable connections at the rear of the projector. They are calculated for a 16:10 image; actual distances should be verified on site and according to the manufacturer's manual.

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

To check whether a model outside the list is compatible, send us a photo of the projector nameplate and the current lens. Projectors based on the same-generation platform often share a mount, but ordering based on a similar model name is not worth the risk.

Throw Ratios for Different Model Series

The nominal throw ratio of the same 118-100116-xx Zoom lens varies by projector series. When selecting a lens, use the value for the series of your actual projector.

Model Series	Throw Ratio
—	6.90-10.40:1

IV. Three Checks Before Replacement

• Confirm the projector panel and resolution. Original lenses are designed for a specific panel size. If the panel specifications differ, the image circle cannot cover the full area, resulting in vignetting or edge light loss.
• Calculate the installation distance first. This lens has a nominal throw ratio of 6.90-10.40:1. Apply the table in Section II to your site dimensions. A fixed-focus lens offers no adjustment margin, and even a zoom lens requires 10–20 cm of margin at both ends.
• Verify the mount and locking mechanism. The original lens is calibrated to the mount of that projector series. After installation, you must hear it lock fully into place. A skewed image or soft edges usually indicate that it is not fully locked, rather than a problem with the lens itself.

If you are unsure, photograph the projector nameplate and the nameplate on the existing lens and send the images to us. Verification against the physical products is the most reliable approach.
