The Christie 121-119102-XX is a high-performance short throw zoom lens engineered for Christie's professional-grade 3-chip DLP and LCD projectors, enabling large-scale image projection from a very short distance. This lens features a 1.5x zoom ratio with a focal length range of 17-26mm and a fast aperture of F1.8-2.3, allowing for significant image size adjustment and placement flexibility in space-constrained environments. The optical design incorporates precision-engineered glass elements with advanced multi-coatings to maximize light throughput, enhance contrast ratio, and minimize optical aberrations such as geometric distortion and chromatic fringing. This ensures a sharp, bright, and color-faithful image even at the edges of the screen, which is critical for applications requiring detailed and immersive visuals.

Constructed with durability and precision in mind, the lens is housed in a robust, machined metal barrel that provides long-term mechanical stability and protects the internal optics from environmental factors. The smooth manual zoom and focus rings allow installers to make fine adjustments to achieve perfect focus and image geometry. Its short throw characteristic is particularly valuable in installations where the projector must be mounted close to the screen, such as in boardrooms, classrooms, museums, and rear-projection setups, overcoming limitations posed by low ceilings, existing architecture, or the need to keep the projector out of sightlines.

This lens is a key component in creating seamless and impactful visual displays, complementing Christie projectors known for their high brightness and resolution. By offering a balance of wide throw flexibility and optical speed, the Christie 121-119102-XX Short Throw Zoom Lens provides system integrators with a reliable tool to achieve optimal image quality in challenging installation scenarios. It enables the creation of large, bright images from a compact footprint, making it an essential choice for fixed installations where space is at a premium but visual impact cannot be compromised.
