Christie 140-100102-xx Zoom Standard Throw Lens for 11 Models

Christie OEM Lens 140-100102-xx Zoom is an OEM optical accessory for Christie engineering projectors, offering a standard throw ratio of 1.22-1.53:1. Its factory compatibility list covers 11 models; before installation, simply verify the projector model and panel size—there is no need to resort to adapter rings. The value of an OEM lens lies not in additional specification figures, but in its factory calibration to the optical path and lens mount of that projector series: once installed, the image circle, edge illumination, and focus travel are all as designed, with no need to use keystone correction to compensate for image quality.

I. Lens Specifications

Brand	Christie (Christie)
Lens Model	140-100102-xx Zoom
Throw Ratio	1.22-1.53:1
Product Type	Standard Throw
Compatible Models	11 models
Warranty	12 months; damage not caused by the user is eligible for after-sales service, subject to the date on the shipping documents

The above specifications are subject to the factory specifications. For mechanical dimensions, flange distance, and mount type not listed in the specifications table, please contact us with your projector model for verification. Ordering solely based on a similar model carries the risk of incompatibility.

II. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of installation distance to image width. This OEM lens is a zoom lens (1.22-1.53:1), so a given image size corresponds to a range of installation distances, and any position within that range can be focused.

Image Size	Image Width	Required Installation Distance
100 inches	2.15 m	Approx. 2.62 – 3.29 m
120 inches	2.58 m	Approx. 3.15 – 3.95 m
150 inches	3.22 m	Approx. 3.93 – 4.93 m
200 inches	4.30 m	Approx. 5.25 – 6.58 m

These figures represent the net distance from the front surface of the lens to the screen and do not include clearance for ventilation and cable connections at the rear of the projector. They are calculated for a 16:10 image; actual values should be verified by on-site measurement and confirmed in the factory manual.

Image quality differs at the two ends of the zoom range: the shorter end produces a brighter image with slightly softer edges, while the longer end delivers sharper edges with slightly lower brightness. Where space permits, the middle of the range is recommended. After installation, find the sharpest setting on the focus ring, then fine-tune the lens shift.

III. Compatible Models (11 Models)

The following table is taken from the factory compatibility list. Brightness and resolution are populated from the model database; unavailable values are marked as “—” and are not inferred.

Model	Brightness	Resolution
DHD550-G	5500 lumens	1920x1080
DHD555-GS White	—	—
DHD555-GS-Black	5000 lumens	1920x1080
DHD600-G	6200 lumens	1920x1080
DHD630-GS	5400 lumens	1920x1080
DHD635-GS	5400 lumens	1920x1080
DWU550-G	5600 lumens	1920x1200
DWU555-GS	5400 lumens	1920x1200
DWU600-G	6300 lumens	1920x1200
DWX555-GS	5400 lumens	1280x800
DWX600-G	6400 lumens	1280x800

To verify compatibility with a model not included in the list, send us photos of the projector nameplate and the existing lens for confirmation—platforms of the same generation often share the same mount, but ordering based on a similar model is not worth the risk.

Throw Ratios by Projector Series

The rated throw ratio varies by series when the same 140-100102-xx Zoom lens is installed. Select the value based on the actual projector series.

IV. Three Checks Before Replacement

• Confirm the projector imaging panel and resolution.OEM lenses are designed for specific panel sizes. 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 rated throw ratio of 1.22-1.53:1. Use the table in Section II to calculate the distance for your installation site. A fixed-focus lens offers no adjustment margin, while a zoom lens should still leave 10–20 cm at both ends of the range.
• Verify the mount and locking mechanism.The OEM lens is calibrated to the mount of that projector series and must audibly lock into place after installation. A skewed image and soft edges are usually caused by incomplete locking rather than a problem with the lens itself.

If you are uncertain, take one photo of the projector nameplate and one of the existing lens nameplate and send them to us. Physical verification is the safest approach.
