Christie Zoom Lens 2.6-4.1:1 ILS1 - 118-100114-03

What is the Christie 118-100114-03 lens?

A 2.6–4.1:1 zoom lens on an ILS1 mount. It is the long-throw option in the ILS1 family, for venues where the projector sits well back from the screen — a booth at the rear of an auditorium, a catwalk in a theatre, or a long hall.

Throw distance

At 2.6–4.1:1 a 10-foot-wide image needs 26 to 41 feet of throw. Measure the distance available, divide by the image width required, and confirm the result falls in that band.

The wide zoom range matters at these distances — it absorbs the difference between where a drawing puts the projector and where the structure actually allows it to go.

Where long throw is specified

Usually because the projection position is fixed by the building rather than chosen. A rear booth keeps the projector away from the audience, out of the acoustic environment and accessible for service without a lift — which is why it remains the preferred position in permanent venues despite requiring a more expensive lens.

Frequently Asked Questions

What throw distance does it cover?

26 to 41 feet for a 10-foot-wide image. Scale proportionally for other widths.

Which projectors take an ILS1 lens?

ILS1 is used across several Christie ranges. Confirm your specific chassis before ordering — Creation Networks checks this as part of the quote.

Why use a rear booth rather than ceiling mounting?

Access and acoustics. A booth keeps the projector out of the room and serviceable without a lift, which over the life of an installation usually outweighs the higher lens cost.

Can Creation Networks specify the right lens?

Yes. We calculate throw against the room drawing and confirm compatibility first. Call 888-230-3661 or email sales@creationnetworks.net.
