The Christie 103-131106-XX 0.8:1 Fixed Lens is an interchangeable, fixed short-throw lens designed for use with a range of Christie LCD projectors, particularly within the LX and LW series. The "XX" in the part number denotes regional or packaging variations (e.g., 103-131106-01), but the core optical specifications remain consistent. This lens provides a fixed 0.8:1 throw ratio, making it suitable for installations where the projector must be positioned close to the screen, such as in auditoriums, conference rooms, or simulation environments where space is limited but a large image is required.

The fixed throw ratio means the distance between the projector and the screen is approximately 0.8 times the width of the projected image. This design choice ensures consistent optical performance and simplifies installation calculations for specific venue requirements. The lens features a bayonet-style mount, allowing for quick and easy user replacement and integration with compatible Christie projector models, including the LX700, LX650, LW300, and others.

The lens is engineered with a specific focal length of 22.33mm and an f-value of 2.5, which helps maintain brightness and image clarity even at shorter projection distances. It also offers limited offset and is designed to work within the standard lens shift capabilities of the compatible projectors, providing flexibility in final image positioning. The robust build quality is typical of professional-grade equipment intended for reliable performance in commercial and staging environments.
