Christie 163-118101-01 HC Zoom Standard Throw Projector Lens: Compatible with Eclipse G3

Christie Original Lens 163-118101-01 HC Zoom is a genuine optical accessory for Christie large-venue projectors, belonging to the standard throw category with a throw ratio of 1.13-1.66:1. The factory compatibility list covers 5 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 about extra rows of numbers in the spec sheet, but 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 all match design values, so you don't need keystone correction to compensate for image quality.

1. Lens Specifications

Brand	Christie
Lens Model	163-118101-01 HC Zoom
Throw Ratio	1.13-1.66:1
Product Type	Standard Throw
Compatible Models	5
Warranty	12 months; after-sales service available for non-human damage, based on the date on the shipping document

The above specifications are subject to the original factory specifications. For mechanical dimensions, flange focal distance, and mount type not shown in the spec table, please verify with us based on 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 a zoom lens (1.13-1.66:1), so the same image size corresponds to a range of distances; as long as installation falls within this range, focus can be achieved.

Image Size	Image Width	Required Installation Distance
100 inches	2.15 m	Approx. 2.43 – 3.57 m
120 inches	2.58 m	Approx. 2.92 – 4.28 m
150 inches	3.22 m	Approx. 3.64 – 5.35 m
200 inches	4.30 m	Approx. 4.86 – 7.14 m

The above values are the clear distance from the lens face to the screen, excluding rear ventilation and cabling space behind the projector. Calculated for 16:10 aspect ratio; actual values are subject to on-site measurement and the original factory manual.

Image quality differs at the two ends of the zoom range: toward the near end the image is brighter with slightly softer edges; toward the far end the edges are sharper with slightly reduced brightness. Where space permits, it is recommended to land in the middle of the range; after installation, first find the sharpest position on the focus ring, then fine-tune the shift.

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

Model	Brightness	Resolution

Griffyn 4K35-RGB	—	—
Griffyn 4K50-RGB	—	—
Sapphire 4K40-RGBH	—	—

For models not on the list, please send us photos of the projector nameplate and the existing lens for verification — same-generation platforms often share mounts, but the risk of ordering based on model similarity alone isn't worth it.

Throw Ratios Across Different Model Series

The same 163-118101-01 HC Zoom installed on the following series has different nominal throw ratios; selection should be based on the actual series of your projector.

Model Series	Throw Ratio
—	1.13-1.66:1

4. Three Things to Confirm Before Replacement

• Confirm the projector chip and resolution. Original lenses are designed for specific panel sizes; if the panel specifications differ, 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 1.13-1.66:1; use the table in Section 2 to map it to your venue dimensions. Prime lenses have no margin, and even zoom lenses need 10–20 cm of clearance at both ends.
• Verify the mount and locking. Original lenses are calibrated to the mount of that projector series; after installation you must hear the lock engage. Image skew and soft edges are mostly due to incomplete locking, not a problem with the lens itself.

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