Christie Original Lens 118-100111-01 Zoom is a genuine optical accessory for Christie installation projectors, belonging to the standard throw category, with a throw ratio of 1.16-1.49:1. The original compatibility list covers 33 models; before installation, simply verify against the projector model and panel size—no adapter rings needed. The value of an original lens isn't in a few extra rows of numbers on a spec sheet, but in the fact that it is calibrated at the factory to the optical path and mount of that series' chassis: once installed, the image circle, edge illumination, and focus travel are all at their design values, with no need to compensate for image quality using keystone correction.
1. Lens Specifications
| Brand | Christie |
| Lens Model | 118-100111-01 Zoom |
| Throw Ratio | 1.16-1.49:1 |
| Product Type | Standard Throw |
| Compatible Models | 33 |
| Warranty | 12 months; after-sales service available for non-human damage, based on the date on the shipping document |
The above specifications are subject to the original manufacturer's specifications. For mechanical dimensions, flange focal distance, and mount type not shown in the spec table, please verify with us against the projector model—ordering based on similar model numbers carries the risk of incompatibility.
2. Converting Throw Ratio to Installation Distance
Throw ratio is the ratio of installation distance to image width. This original lens is a zoom lens (1.16-1.49:1), so the same image size corresponds to a range of distances; as long as installation falls within this range, focus can be achieved.
| Image Size | Image Width | Required Installation Distance |
|---|---|---|
| 100 inches | 2.15 m | Approx. 2.49 – 3.20 m |
| 120 inches | 2.58 m | Approx. 2.99 – 3.84 m |
| 150 inches | 3.22 m | Approx. 3.74 – 4.81 m |
| 200 inches | 4.30 m | Approx. 4.99 – 6.41 m |
The above figures are the clear distance from the lens face to the screen, excluding rear ventilation and cabling space. Calculated for 16:10 aspect ratio; actual values are subject to on-site measurement and the original manufacturer's manual.
Image quality differs at the two ends of the zoom range: toward the near end the image is brighter with slightly softer edges; toward the far end the edges are sharper with slightly reduced brightness. Where space permits, it is recommended to land in the middle of the range; after installation, first find the sharpest position on the focus ring, then fine-tune the shift.

To determine whether models outside the list can be used, please send us photos of the projector nameplate and the existing lens for verification—same-generation platforms often share mounts, but ordering based on similar model numbers is a risk not worth taking.
Throw Ratios Across Model Series
The same 118-100111-01 Zoom installed on the following series does not have the same nominal throw ratio; selection must be based on the actual series of the projector.
| Model Series | Throw Ratio |
|---|---|
| — | 1.16-1.49:1 |
4. Three Things to Confirm Before Replacement
- Confirm the projector chip and resolution. Original lenses are designed for specific panel sizes; if the panel specifications differ, the image circle cannot cover it, resulting in vignetting or edge light loss after installation.
- Calculate the installation distance first. This lens has a nominal throw ratio of 1.16-1.49:1; use the table in Section 2 to match your venue dimensions. Fixed focal length has no margin, and even zoom lenses should leave 10–20 cm at both ends.
- Verify the mount and locking. Original lenses are calibrated to the mount of that series' chassis; after installation, you must hear the lock engage. Image skew and soft edges are mostly due to incomplete locking, not a problem with the lens itself.
If unsure, take a photo of the projector nameplate and the existing lens nameplate and send them to us—verification against the actual hardware is the safest approach.
