Sharp (SIICA) short-throw zoom lens is designed for projector use to deliver flexible placement and simplified setup in meeting rooms, classrooms, and installation environments. The lens supports a short-throw projection range with a 0.79-1.11:1 throw ratio and a 13.3 mm to 18.6 mm focal length range, enabling large images from close distances while preserving image quality. Motorized zoom and focus, together with a 1.4x optical zoom and an f/2.0-2.5 aperture, help achieve accurate framing and maintain brightness, making installation and adjustments faster and more precise.
