Christie 144-136101-01 UST Fixed Lens for 5 Compatible Models

Christie Genuine Lens 144-136101-01 UST Fixed is a genuine optical accessory for Christie professional projectors. It is an Ultra Short Throw (UST) lens with a 0.38:1 throw ratio. The manufacturer's compatibility list covers 5 models; before installation, simply check the projector model and panel size, with no adapter-ring workaround needed. The value of a genuine lens lies not in the extra numbers it adds to the specifications table, 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 focus travel are all at their design values, so there is no need to use keystone correction to compensate for the image.

1. Lens Specifications

The above specifications are based on the manufacturer's official specifications. For mechanical dimensions, flange distance, and mount type not listed in the specifications table, please contact us with the projector model so we can verify them. Ordering solely on the basis of 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 genuine lens has a fixed throw ratio (0.38:1), so the installation distance varies linearly with image size and offers no adjustment margin. Measurements must be taken accurately before installation.

The values above represent the clear distance from the front face of the lens to the projection screen and do not include space behind the projector for cooling and cable connections. For a 16:10 image, actual values should be verified on site and against the manufacturer's manual.

3. Compatible Projector Models (5 Models)

The table below is taken from the manufacturer's compatibility list. Brightness and resolution have been added from the model database; where data is unavailable, "—" is shown, and no values are estimated.

For use with a model not on the list, please send us the projector nameplate and a photo of the existing lens for verification. Platforms from the same generation often share a mount, but the risk of ordering based on a similar model name is not worth taking.

Throw Ratios by Projector Series

The nominal throw ratio of the same 144-136101-01 UST Fixed lens varies across the series listed below. When selecting a lens, use the value for the series of the projector in use.

4. Three Checks Before Replacement

• Confirm the projector chip and resolution. Genuine lenses are designed for a specific panel size. If the panel specifications differ, the image circle cannot cover the full image, causing vignetting or edge light loss after installation.
• Calculate the installation distance first. This lens has a nominal throw ratio of 0.38:1; use the table in Section 2 to determine the distance for your installation site. A fixed-focus lens has no adjustment margin; even with a zoom lens, allow 10–20 cm at both ends.
• Check the mount and locking mechanism. Genuine lenses are calibrated to the mount of that projector series. After installation, you must hear the locking mechanism engage fully. A skewed image or soft edges usually indicate that the lens is not fully locked, rather than a problem with the lens itself.

If you are unsure, photograph the projector nameplate and the nameplate on the existing lens, and send the photos to us. Verification against the physical equipment is the most reliable approach.
