Christie Lens 1.52-2.89 Zoom G/GS - 140-102104-02

Product Overview

The Christie 140-102104-02 is a 1.52-2.89:1 zoom lens for Christie G and GS Series 1DLP projectors. Its nearly 2x zoom range covers the standard-throw distances most installations call for, making it the most versatile single lens in the G/GS lineup. Compatibility spans the G Series (DHD550-G, DHD600-G, DWU550-G, DWU600-G, DWX600-G) and the GS Series, including DHD555-GS through DHD1075-GS and DWU555-GS through DWU1075-GS models.

Product Description

Most fixed installations place the projector between one and a half and three image-widths from the screen, and the 140-102104-02 covers exactly that band. With a 1.52-2.89:1 throw ratio, a single lens accommodates classrooms, boardrooms, lecture halls, and mid-sized venues without swapping optics — the projector can be positioned across a wide range of ceiling mount locations and still fill the screen precisely. The broad zoom range is equally useful in rental work, where one lens covers the majority of room geometries a GS Series projector will encounter. Compatibility extends across two projector generations: the lamp-based G Series and the laser-phosphor GS Series up through the 1075 models, which protects the investment as fleets are upgraded. The lens exchanges with shorter and longer G/GS options in the field. As genuine Christie glass, it preserves the resolution and brightness uniformity the projectors are specified to deliver.
