Christie 130-100102-01 Fixed Short-Throw Lens Review: Mirage WU-L Fit

Christie Original Lens 130-100102-01 Fixed is an OEM optical accessory for Christie engineering projectors. It is a short-throw lens with a throw ratio of 0.64:1. The OEM compatibility list covers one model. Before installation, simply verify the projector model and panel size; no adapter ring workaround is needed. The value of an OEM lens lies not in the additional figures in its specification sheet, but in its factory calibration to the optical path and mount of the corresponding projector series: once installed, the image circle, edge illumination, and focusing travel all operate at their designed values, eliminating the need to compensate for image quality with keystone correction.

1. Lens Specifications

The above specifications are subject to the OEM specifications. For mechanical dimensions, flange distance, and mount type not listed in the specification table, please contact us with the projector model for verification. Ordering solely on the basis of a similar model risks a lens that 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 OEM lens has a fixed focal length (0.64:1), so the installation distance varies linearly with image size, with no adjustment margin. Accurate measurements are therefore essential before installation.

The values above represent the clear distance from the front surface of the lens to the screen and do not include space behind the projector for cooling and cable connections. They are calculated for a 16:10 image; actual values should be confirmed through on-site measurement and the OEM manual.

3. Compatible Models (1 model)

The table below is taken from the OEM compatibility list. Brightness and resolution are populated from the model database; entries that cannot be obtained are marked “—” and are not estimated.

For compatibility with models outside this list, send us photos of the projector nameplate and existing lens for verification—same-generation platforms often share the same mount, but the risk of ordering based only on a similar model is not worth taking.

Throw Ratio by Projector Series

The nominal throw ratio differs by series even when the same 130-100102-01 Fixed lens is installed. Select the value based on the series of the actual projector.

4. Three Checks Before Replacement

• Confirm the projector imaging 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 area, resulting in vignetting or light loss at the edges.
• Calculate the installation distance first. Use the table in Section 2 to calculate the distance based on your installation site dimensions. A fixed-focal-length lens offers no adjustment margin, while a zoom lens should have 10–20 cm of clearance at both ends.
• Verify the mount and locking mechanism. The OEM lens is calibrated to the mount of the relevant projector series, and you must hear it lock securely into place after installation. Image skew or soft edges are usually caused by incomplete locking, not by a defect in the lens.

If you are unsure, take one photo of the projector nameplate and one of the existing lens nameplate, then send them to us. Verification against the physical unit is the safest option.
