The Christie 104-110101-01 is an ultra-wide fixed focal length (prime) lens engineered for large-venue Christie projectors with 0.95-inch DLP technology, offering exceptionally short throw capabilities. With a fixed throw ratio of 0.73:1 for SXGA+ models and 0.67:1 for HD models, this lens is designed for the shortest possible projection distances, allowing the projector to be positioned extremely close to the screen—often just a small fraction of the screen's width away. This makes it an indispensable solution for installations where space is severely constrained, such as in tight control rooms, interactive floor or table projections, rear-projection boxes with minimal depth, or architectural installations where the projector must be almost touching the screen or completely hidden from view.

As a fixed lens, it prioritizes optical performance and maximum light transmission over flexibility. The simple optical path with no zoom mechanism typically allows for a very large maximum aperture, which helps preserve the projector's high brightness output—a critical factor when projecting from such an acute angle where light falloff can be a challenge. The lens is constructed with precision glass elements in a robust housing to maintain image sharpness and minimize geometric distortion (like pincushion or barrel distortion) that can be more pronounced in ultra-short-throw applications. For system designers tackling unique spatial challenges, the Christie 104-110101-01 provides the key to creating large, immersive images from seemingly impossible projector placements, enabling creative and space-efficient visual displays.
