Christie 140-133108-XX Ultra Short Lens: Compatible with 5 Projector Models

Christie Original Lens 140-133108-XX Ultra Short is an OEM optical accessory for Christie engineering projectors. It is an ultra-short-throw (Ultra Short Throw) lens with a throw ratio of 0.36:1. The OEM compatibility list covers 5 models; before installation, simply verify the projector model and panel size—no adapter rings are needed. The value of an OEM lens lies not in the extra rows of specifications, but in its factory calibration to the optical path and mount of that projector series. Once installed, the image circle, edge illumination, and focusing travel all meet their design values, eliminating the need to use keystone correction to compensate for image quality.

1. Lens Specifications

These specifications are subject to the OEM specifications. For mechanical dimensions, flange distance, and lens mount type not shown in the specifications table, please contact us with the projector model. Ordering solely based on a similar model carries the risk that the lens will not fit.

2. Calculating Installation Distance from the Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This OEM lens has a fixed throw ratio (0.36:1), so the installation distance varies linearly with the image size and offers no adjustment margin. Accurate measurements are essential before installation.

These figures represent the clear distance from the front surface of the lens to the screen and do not include clearance behind the projector for cooling and cable connections. They are calculated for a 16:10 image; actual installation should follow on-site measurements and the OEM manual.

3. Compatible Models (5 Models)

The following table is taken from the OEM compatibility list. Brightness and resolution are populated from the model database; unavailable data is marked as “—” without making assumptions.

To determine whether a model outside the list is compatible, send us photos of the projector nameplate and the existing lens for verification. Same-generation platforms often share the same mount, but ordering based solely on a similar model is not worth the risk.

Throw Ratio by Model Series

The nominal throw ratio varies by series when the same 140-133108-XX Ultra Short lens is installed. Use the value for the actual projector series when selecting a lens.

4. 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, resulting in vignetting or edge light loss after installation.
• Calculate the installation distance first. This lens has a rated throw ratio of 0.36:1; use the table in Section 2 to calculate the distance for your installation site. A fixed-focal-length lens offers no adjustment margin, and even a zoom lens should leave 10–20 cm at both ends.
• Verify the mount and locking mechanism. The OEM lens is calibrated to the mount of that projector series. After installation, confirm that the locking mechanism clicks into place. Image skew and soft edges are usually caused by incomplete locking, not by a faulty lens.

If you are unsure, send us one photo each of the projector nameplate and the current lens nameplate. Verification against the actual hardware is the safest approach.
