The
ET-DLE250 is an essential optic for long-throw applications where the projector must be positioned well behind the audience. Featuring a powerful
1.56x motorized zoom, it allows for precise image scaling from distances that standard lenses cannot reach. Its optical construction is optimized for 4K and WUXGA laser light engines, maintaining a fast
f/2.0–2.4 aperture to ensure minimal light drop-off even at maximum focal length.
