The Digital Projection 115-339 is a variable wide-angle zoom with a 0.75–0.93:1 throw ratio on WUXGA E-Vision models (and 0.74–0.93:1 on 4K-UHD). It features motorized zoom/focus and is commonly listed as compatible with E-Vision Laser 6900, 8500, 10K, 11,000/13,000 and 4K projectors, giving you a broad fit across the E-Vision family. 

For planning, use throw distance = screen width x ratio. Falling within the wide-angle band (0.60–1.30:1), this lens enables large images from short distances with precise adjustment after installation.
