The Christie 38-809036-XX 1.2:1 Short Throw High Precision Fixed Projector Lens is an all-glass optical component designed to offer versatility and high performance for a range of professional projectors, including legacy RoadRunner, Vivid, and select LX series models. It provides multiple throw ratios depending on the specific projector body it is paired with, such as 1.2:1 with LU77, and 1.5:1 with LS+58, allowing flexibility for various installation environments where screen distance is limited. The all-glass construction ensures better focus and thermal stability compared to lenses made with other materials, maintaining image integrity even during extended use.

This fixed lens offers precise image control, featuring adjusters for corners, pincushion, and tilt, which simplifies setup for standard and multi-array images. Its design is intended to provide a high-brightness solution, ensuring vibrant images when paired with a compatible projector. The lens's robust optical performance makes it suitable for demanding professional applications where maintaining a high-quality, stable image is crucial.

Physically, the lens is built to integrate seamlessly with specific Christie projector models and is designed to be easily installed and removed when needed. Its mechanical specifications, including a substantial maximum diameter and focal length, are optimized for short-throw scenarios to produce large images from relatively close distances. This design minimizes the space required for the projection setup while maximizing the projected image size.
