Christie 130-102104-XX Fixed Short Throw Projector Lens: Mirage WQ-L & WU-L Compatible

Christie Original Lens 130-102104-XX Fixed is a genuine optical accessory for Christie installation projectors, belonging to the short throw category, with a throw ratio of 0.80:1. The original compatibility list covers 2 projector models; before installation, simply verify against the projector model and panel size — no adapter rings needed. The value of an original lens isn't in a few extra rows of numbers on a spec sheet, but in the fact that it is calibrated at the factory to the optical path and bayonet of that series' chassis: once mounted, the image circle, edge illumination, and focus travel are all at their design values, with no need to compensate image quality via keystone correction.

1. Lens Specifications

Brand	Christie
Lens Model	130-102104-XX Fixed
Throw Ratio	0.80:1
Product Type	Short Throw
Compatible Models	2
Warranty	12 months; non-human-caused damage is eligible for after-sales service, based on the date on the shipment document

The above specifications are subject to the original manufacturer's specifications. For mechanical dimensions, flange focal distance, and bayonet type not shown in the spec table, please verify with us against your projector model — ordering based on model similarity alone carries the risk of incompatibility.

2. Converting Throw Ratio to Installation Distance

Throw ratio is the ratio of installation distance to image width. This original lens is fixed focal length (0.80:1), so the installation distance changes linearly with image size and has no adjustment margin — it must be measured accurately before installation.

Image Size	Image Width	Required Installation Distance
100 inch	2.15 m	approx. 1.72 m
120 inch	2.58 m	approx. 2.06 m
150 inch	3.22 m	approx. 2.58 m
200 inch	4.30 m	approx. 3.44 m

The above figures are the clear distance from the lens front to the screen, excluding rear ventilation and cabling space behind the projector body. Calculated at 16:10 aspect ratio; actual values are subject to on-site measurement and the original manufacturer's manual.

3. Compatible Models (2)

The table below is taken from the original compatibility list; brightness and resolution are filled in from the model database, with "—" where unavailable — no speculation.

Model	Brightness	Resolution
Mirage WQ-L	—	—
Mirage WU-L	—	—

To determine whether models outside the list are usable, please send us photos of the projector nameplate and the existing lens for verification — same-generation platforms often share a bayonet, but the risk of ordering based on model similarity alone isn't worth it.

Throw Ratios Across Different Model Series

The same 130-102104-XX Fixed lens, when mounted on the following series, does not have the same nominal throw ratio; selection must use the value for the series your actual projector belongs to.

Model Series	Throw Ratio
—	0.80:1

4. Three Things to Confirm Before Replacement

• Confirm the projector's chip and resolution. Original lenses are designed for specific panel sizes; with a different panel specification, the image circle cannot cover it, resulting in vignetting or edge light loss after installation.
• Calculate the installation distance first. This lens has a nominal throw ratio of 0.80:1; apply it to your venue dimensions using the table in Section 2. Fixed focal length has no margin, and even zoom lenses should leave 10–20 cm at both ends.
• Verify the bayonet and locking. Original lenses are calibrated to the bayonet of that series' chassis; after mounting, you must hear it lock into place. Skewed images and soft edges are mostly due to incomplete locking, not a problem with the lens itself.

If unsure, take one photo each of the projector nameplate and the existing lens nameplate and send them to us — verification against the actual hardware is the safest approach.
