Christie Genuine Lens 144-107109-01 HB Zoom is an original optical accessory for Christie engineering projectors. It is a long-throw lens (Long Throw) with a throw ratio of 2.71-3.89:1. The OEM compatibility list covers 14 models; before installation, simply verify the projector model and panel size, with no need to make do with adapter rings. The value of an OEM lens lies not in the additional figures in a specification sheet, but in the fact that it is factory-calibrated to the optical path and mount of that projector series: once installed, the image circle, edge illumination, and focus travel all meet the design values, eliminating the need to use keystone correction to compensate for image quality.
I. Lens Specifications
| Brand | Christie (Christie) |
| Lens Model | 144-107109-01 HB Zoom |
| Throw Ratio | 2.71-3.89:1 |
| Product Type | Long Throw |
| Compatible Models | 14 models |
| Warranty | 12 months; after-sales service is available for damage not caused by the user, based on the date shown on the shipping documents |
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 based solely on a similar model carries the risk that the lens will not fit.
II. Calculating Installation Distance from Throw Ratio
The throw ratio is the ratio of installation distance to image width. This genuine lens is a zoom lens (2.71-3.89:1), so each image size corresponds to a range of installation distances. It can focus at any distance within that range.
| Image Size | Image Width | Required Installation Distance |
|---|---|---|
| 100 inches | 2.15 m | Approx. 5.83 – 8.36 m |
| 120 inches | 2.58 m | Approx. 6.99 – 10.04 m |
| 150 inches | 3.22 m | Approx. 8.74 – 12.55 m |
| 200 inches | 4.30 m | Approx. 11.65 – 16.73 m |
These figures represent the clear distance from the front lens element to the screen and do not account for space behind the projector for cooling and cable connections. They are calculated for a 16:10 aspect ratio; in practice, rely on on-site measurements and the OEM manual.
Image quality varies at the two ends of the zoom range: toward the short-throw end, the image is brighter and the edges are slightly softer; toward the long-throw end, the edges are sharper and brightness decreases slightly. When the venue allows, it is recommended to position the lens near the middle of the range. After installation, turn the focus ring to the sharpest position, then fine-tune the lens shift.
III. Compatible Models (14 Models)
The following table is taken from the OEM compatibility list. Brightness and resolution are populated from the model database; where the data cannot be obtained, “—” is shown, and no values are estimated.
| Model | Brightness | Resolution |
|---|---|---|
| Boxer 2K20 | — | — |
| Boxer 2K25 | — | — |
| Boxer 2K30 | — | — |
| Boxer 30 | — | — |
| Boxer 4K20 | — | — |
| Boxer 4K30 | — | — |
| D4K40-RGB | 40000 lumens | 4096x2160 |
| Eclipse G3 | — | — |
| Griffyn 4K32-RGB | — | — |
| Griffyn 4K35-RGB | — | — |
| Griffyn 4K50-RGB | — | — |
| Mirage 304K | — | — |
| Mirage 4K40-RGB | — | — |
| Sapphire 4K40-RGBH | — | — |
To determine whether a model outside the list is supported, please send us photos of the projector nameplate and existing lens for verification—platforms of the same generation often share mounts, but the risk of ordering based on a similar model is not worth taking.
Throw Ratio by Projector Model Series
When the same 144-107109-01 HB Zoom lens is installed on the following series, the nominal throw ratio varies. Use the value corresponding to the series of the actual projector when selecting a lens.
| Model Series | Throw Ratio |
|---|---|
| — | 2.71-3.89:1 |
IV. Three Checks Before Replacement
- Confirm the projector chip and resolution. The OEM lens is designed for a specific panel size. If the panel specifications differ, the image circle cannot cover the full image area, resulting in vignetting or light loss at the edges after installation.
- Calculate the installation distance first. This lens has a nominal throw ratio of 2.71-3.89:1. Apply the table in Section II to the dimensions of your venue. A fixed-focus lens provides no adjustment margin, and even a zoom lens requires a 10–20 cm allowance at both ends of the range.
- Verify the mount and locking mechanism. The OEM lens is calibrated to the mount of that projector series, and you must hear it lock into place after installation. A skewed image or soft edges are usually caused by incomplete locking, not by a problem with the lens itself.
If you are unsure, send us one photo each of the projector nameplate and the existing lens nameplate. Verification against the physical items is the most reliable approach.
