Christie 144-104106-01 HB Zoom Standard-Throw Lens: Compatible with 14 Christie Models

Christie OEM Lens 144-104106-01 HB Zoom is an OEM optical accessory for Christie engineering projectors, featuring a Standard Throw (Standard Throw) with a throw ratio of 1.31-1.63:1. The official compatibility list covers 14 models; simply verify the projector model and panel size before installation—no adapter rings needed. The value of an OEM lens lies not in extra rows of specifications, but in the fact that it is calibrated at the factory to the optical path and mount of the corresponding model series: once installed, the image circle, edge illumination, and focusing travel all meet their design values, eliminating the need to compensate for image quality with keystone correction.

I. Lens Specifications

These specifications are subject to the manufacturer's official specifications. For mechanical dimensions, flange distance, and mount type not listed in the specifications table, contact us with the exact projector model for verification. Ordering based solely on a similar model risks a mismatch that may prevent installation.

II. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This OEM lens is a zoom lens (1.31-1.63:1), so a given image size corresponds to a range of distances, and the lens can focus anywhere within that range during installation.

These are net distances from the front of the lens to the screen and do not account for rear housing clearance for heat dissipation and cable connections. The values are calculated for a 16:10 image; actual dimensions must be verified on site and according to the manufacturer's manual.

Image quality varies between the two ends of the zoom range: at the near end, the image is brighter and the edges appear slightly softer; at the far end, the edges are sharper and the image slightly dimmer. When the venue allows, use a position near the middle of the range. After installation, first find the sharpest position on the focus ring, then fine-tune the lens shift.

III. Compatible Models (14 Models)

The following table is taken from the official compatibility list. Brightness and resolution are populated from the model database; where unavailable, they are marked "—" and are not estimated.

For models not listed, send us photos of the projector nameplate and the current lens so we can verify compatibility—models from the same generation often share the same mount, but ordering based on a similar model carries unnecessary risk.

Throw Ratios by Model Series

The nominal throw ratio of the same 144-104106-01 HB Zoom varies across the series listed below. Select the value based on the series of the projector in use.

IV. Three Checks Before Replacement

• Confirm the projector chip and resolution. OEM lenses are 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 nominal throw ratio of 1.31-1.63:1; apply the table in Section II to your venue dimensions. A fixed-focus lens offers no adjustment margin, and even a zoom lens requires 10–20 cm of clearance at both ends of the range.
• Verify the mount and locking mechanism. OEM lenses are calibrated to the mounts of the corresponding projector series, and you must hear the lens click fully into the locked position after installation. A skewed image or soft edges usually indicate that the lens is not fully locked, rather than a fault in the lens itself.

If you are unsure, send us one photo each of the projector nameplate and the nameplate on the current lens. Verification against the actual equipment is the most reliable approach.
