The Buhl 732MCZ151 is a professional-grade, high-brightness zoom lens engineered for large-venue and high-output digital projectors, specifically those requiring a medium to long throw distance. This lens is meticulously designed to maximize light transmission and maintain image integrity, making it a critical component for applications where both brightness and image sharpness are non-negotiable. It is commonly paired with high-lumen 3-chip DLP and LCD projectors used in demanding environments such as large houses of worship, auditoriums, performing arts centers, and simulation facilities. The lens construction focuses on minimizing light loss through advanced optical coatings and precision-ground glass elements, ensuring the projector's full luminous output is delivered to the screen with exceptional clarity.

Its optical design features a versatile zoom and focus range, providing installers with significant flexibility in projector placement relative to the screen size. The XTRA Bright designation signifies its use of specialized multi-element lens groups and anti-reflective coatings that are optimized for the specific spectral output of high-intensity projection lamps, thereby enhancing overall efficiency and contrast. The robust, all-metal housing ensures precise alignment is maintained over time, protecting the internal optics from dust, vibration, and thermal shifts that are common in professional installations. This durability is essential for permanent installations where reliability and consistent performance over thousands of hours are required.

The lens incorporates standard industry mounting interfaces, allowing for straightforward integration with compatible projector models from major manufacturers. The manual zoom and focus controls are designed for precise, tool-free adjustments during installation and fine-tuning. By delivering a bright, uniformly illuminated, and geometrically accurate image even at extended throw distances, the Buhl 732MCZ151 serves as a key enabler for creating impactful large-scale visuals, ensuring that the inherent power of a high-performance projector is fully realized on the screen.
