Christie 144-110103-XX HB Fixed Short-Throw Projector Lens Guide: 15 Models

Christie OEM Lens 144-110103-XX HB Fixed is an OEM optical accessory for Christie professional projectors. It is a short-throw (Short Throw) lens with a 0.72:1 throw ratio. The OEM compatibility list covers 15 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 a few extra rows of specifications, but in the fact that it is calibrated at the factory to the optical path and mount of that projector series. Once installed, the image circle, edge illumination, and focusing travel all meet the design values, so there is no need to compensate for image quality with keystone correction.

1. Lens Specifications

Brand	Christie (Christie)
Lens Model	144-110103-XX HB Fixed
Throw Ratio	0.72:1
Product Type	Short-throw (Short Throw)
Compatible Models	15 models
Warranty	12 months; for damage not caused by the user, after-sales service applies, based on the date on the shipping invoice

The above specifications are subject to the manufacturer's official specifications. For the mechanical dimensions, flange distance, and mount type not shown in the specifications table, please verify them with us against the projector model; ordering solely on the basis of a similar model name carries the risk that the lens will not fit.

2. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This OEM lens has a fixed throw ratio of 0.72:1. The installation distance varies linearly with image size and offers no adjustment margin, so accurate measurements are essential before installation.

Image Size	Image Width	Required Installation Distance
100 inches	2.15 m	approx. 1.55 m
120 inches	2.58 m	approx. 1.86 m
150 inches	3.22 m	approx. 2.32 m
200 inches	4.30 m	approx. 3.10 m

The distances above are the clear distances from the front surface of the lens to the screen and do not account for rear chassis clearance required for ventilation and cabling. They are calculated for a 16:10 image; actual on-site measurements and the manufacturer's manual take precedence.

For models outside 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 the risks of ordering based on a similar model name are not worth taking.

Throw Ratio by Projector Series

The rated throw ratio varies when the same 144-110103-XX HB Fixed lens is fitted to the series listed below, so use the value corresponding to the series of your actual projector.

Model Series	Throw Ratio
—	0.72:1

4. Three Checks Before Replacement

• Confirm the projector's imaging chip and resolution.OEM lenses are designed for a specific panel size. With a different panel specification, the image circle cannot provide full coverage, resulting in vignetting or light loss at the edges after installation.
• Calculate the installation distance first.Apply the rated 0.72:1 throw ratio of this lens and the table in Section 2 to your venue's screen dimensions. A fixed-focus lens offers no adjustment margin, and even a zoom lens requires an additional 10–20 cm of clearance at both ends.
• Verify the mount and locking mechanism.OEM lenses are calibrated to the mount of the corresponding projector series, and you must hear the lens click into the locked position after installation. A skewed image or soft edges are usually caused by an incomplete lock, not by a problem with the lens itself.

If you are unsure, take one photo of the projector nameplate and one of the existing lens nameplate and send them to us. Verification against the actual hardware is the most reliable approach.
