The Christie CT HD 1.40–1.80:1 is a standard zoom lens designed for select Christie 3‑chip DLP projectors, delivering flexible throw options and crisp, high‑brightness imaging for professional venues. With a throw ratio of 1.40–1.80:1, it enables accurate placement in auditoriums, conference centres and live events, making it easier to match image size to room geometry without compromising quality.
Use the throw ratio to plan your setup: distance = image width × ratio. For example, a 5 m wide screen will require approximately 7.0–9.0 m throw distance with this lens. Conversely, image width = distance ÷ ratio. This range gives technicians the latitude to fine‑tune framing and focus while maintaining edge‑to‑edge sharpness.
Engineered for Christie’s high‑performance projector platforms, the CT HD 1.40–1.80:1 supports reliable, repeatable results in demanding installations and touring environments. It’s an excellent choice for medium throw applications where flexibility and clean, professional visuals are essential.
