Christie 144-106108-XX HB Zoom Long Throw Projector Lens: Compatible with 12 Models Including Boxer

Christie Original Lens 144-106108-XX HB Zoom is a genuine optical accessory for Christie large-venue projectors, belonging to the long-throw category with a throw ratio of 1.99-2.71:1. The original compatibility list covers 12 projector models; before installation, simply verify against the projector model and panel size—no adapter rings needed. The value of an original lens isn't about a few extra rows of numbers on a spec sheet, but that it is calibrated at the factory to the optical path and lens mount of that projector series: once mounted, the image circle, edge illumination, and focus travel all match design values, so you don't need keystone correction to compensate for image quality.

1. Lens Specifications

The above specifications are subject to the original manufacturer's specifications. For mechanical dimensions, flange focal distance, and lens mount type not shown in the spec table, please verify with us against your projector model—ordering based on model similarity alone carries the risk of incompatibility.

2. Throw Ratio and Installation Distance Conversion

Throw ratio is the ratio of installation distance to image width. This original lens is a zoom lens (1.99-2.71:1), so the same image size corresponds to a range of distances; as long as installation falls within this range, focus can be achieved.

The above figures are the net distance from the lens front to the screen, excluding rear ventilation and cabling space behind the projector. 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, we recommend positioning in the middle of the range; after installation, first find the sharpest point on the focus ring, then fine-tune the shift.

3. Compatible Models (12)

The table below is taken from the original compatibility list; brightness and resolution are filled in from the model database, with "—" where unavailable—no speculation.

To determine whether models outside this list are compatible, please send us photos of the projector nameplate and the existing lens for verification—same-generation platforms often share lens mounts, but ordering based on model similarity alone is a risk not worth taking.

Throw Ratios Across Model Series

The same 144-106108-XX HB Zoom mounted on the following series has different nominal throw ratios; selection must be based on the actual projector's series.

4. Three Things to Confirm Before Replacement

• Confirm the projector chip and resolution. Original lenses are designed for specific panel sizes; with different panel specifications, the image circle cannot cover the screen, resulting in vignetting or edge light loss after installation.
• Calculate the installation distance first. This lens has a nominal throw ratio of 1.99-2.71:1; use the table in Section 2 to match your venue dimensions. Prime lenses have no margin, and even with zoom, allow 10–20 cm at both ends.
• Verify the lens mount and locking. Original lenses are calibrated to the lens mount of that projector series; after installation, you must hear the lock click into place. Image skew and soft edges are usually caused by incomplete locking, not 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 most reliable approach.
