Christie 113-104106-XX HB Fixed Short-Throw Lens Guide: 7 Compatible Models

Christie Genuine Lens 113-104106-XX HB Fixed is an OEM optical accessory for Christie engineering projectors. It is a short-throw lens with a throw ratio of 0.72:1. The factory compatibility list covers 7 models; before installation, simply verify the projector model and panel size—no adapter rings required. The value of an OEM lens lies not in the extra figures in its 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 focus travel are all at their design values, so there is no need to use keystone correction to compensate for image quality.

1. Lens Specifications

These specifications are subject to the factory specifications. For mechanical dimensions, flange distance, and mount type not listed in the specification table, please contact us with the projector model for verification. Placing an order based solely on a similar model carries the risk that the lens will not fit.

2. Converting Throw Ratio to Installation Distance

The throw ratio is the ratio of the installation distance to the image width. This genuine lens has a fixed focal length (0.72:1), so the installation distance changes linearly with image size, with no adjustment margin. Accurate measurements are essential before installation.

These figures represent the clear distance from the front face of the lens to the screen and do not include space behind the projector for ventilation and cable connections. They are calculated for a 16:10 image; actual installation should be based on on-site measurements and the factory manual.

3. Compatible Models (7 Projectors)

The table below is taken from the factory compatibility list. Brightness and resolution are populated from the model database; unavailable values are shown as “—”, with no assumptions made.

To check whether a model outside the list is compatible, please send us photos of the projector nameplate and the existing lens. Platforms from the same generation often share the same mount, but ordering based on a similar model is not worth the risk.

Throw Ratio by Projector Series

The nominal throw ratio for the same 113-104106-XX HB Fixed lens varies across the series listed below. When selecting a lens, use the value corresponding to the series of the actual projector.

4. Three Checks Before Replacement

• Confirm the projector's imaging chip and resolution. OEM lenses are designed for a specific panel size. If the panel specifications differ, the image circle cannot provide full coverage, resulting in vignetting or edge light loss after installation.
• Calculate the installation distance first. Use the table in Section 2 to match the lens to your site's dimensions. A fixed-focal-length lens offers no adjustment margin; even with a zoom lens, allow 10–20 cm at both ends.
• Verify the mount and locking mechanism. The OEM lens is calibrated to the mount for that projector series, and you must hear it click into the locked position after installation. 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, take one photo of the projector nameplate and one of the current lens nameplate, then send them to us. Verification against the physical units is the most reliable approach.
