Christie Zoom Lens 1.25-2.0:1 Full ILS for Korus Series - 140-165103-01

What is the Christie 140-165103-01 zoom lens?

This is the standard zoom lens for the Christie Korus Series, covering a 1.25–2.0:1 throw ratio with full Intelligent Lens System support and 4K compatibility. It fits the Korus 4K1000-KS and 4K1400-KS, both of which ship as no-lens bodies.

Working out whether this is the right lens

Throw ratio is the distance from lens to screen divided by image width. Measure the distance you actually have, decide the image width the room needs, and divide — if the answer falls between 1.25 and 2.0, this lens covers it.

In practice that means a 10-foot-wide image from 12.5 to 20 feet back, which covers most conference rooms, lecture halls and worship spaces. For shorter distances, the 0.5–0.65:1 short zoom (140-166104-01) is the alternative.

Full ILS matters on a Korus

Full Intelligent Lens System means motorised zoom, focus and lens shift with position memory. On a ceiling-mounted projector that is the difference between adjusting the image from the floor and getting a ladder out. On a multi-projector blend it means lenses recall to saved positions rather than being realigned by hand.

The lens is a required line item

Korus projectors are supplied without a lens so the optic matches the room. A Korus ordered without a lens cannot produce an image — this is not an accessory.

Frequently Asked Questions

Which Korus projectors does this fit?

Both — the 4K1000-KS at 10,050 lumens and the 4K1400-KS at 14,250 lumens. The lens mount is common across the series.

What image size will it produce?

It depends on throw distance. At 1.25:1 a 10-foot image needs 12.5 feet; at 2.0:1 the same image needs 20 feet. Creation Networks calculates this against your room drawing.

What if my throw distance is shorter?

The 0.5–0.65:1 short zoom lens (140-166104-01) covers shorter distances on the same projectors.

Does the projector include a lens?

No. Korus Series projectors ship as no-lens bodies so the optic can be matched to the room.

Can Creation Networks specify the right lens?

Yes. We calculate throw and lens shift against your room drawing before anything is ordered, which is cheaper than discovering the wrong lens on install day. Call 888-230-3661 or email sales@creationnetworks.net.
