Fresnel ALR Floor Rising Screen
Fresnel Anti-Light Floor Rising Screen is a specialized projection surface featuring a unique optical structure with concentric circular grooves (Fresnel lens pattern).
Designed for projectors with medium to long throw distances (typically 1.5:1 to 4:1 throw ratio), this screen combats ambient light interference while providing high-gain,
wide-viewing-angle performance. Its floor-rising mechanism allows for hidden storage when not in use.
Main Features
Fresnel Lens Technology: Concentric circular grooves reject ambient light from above/side sources while directing projected light toward viewers.
Ambient Light Rejection (ALR): Special optical coating and structure maintain image quality in moderately lit environments (up to 150 lux).
Medium-Long Throw Optimization: Works best with projectors installed 1.5x to 4x the screen width away from the surface.
High Gain: Enhances brightness perception while maintaining wide 160° horizontal viewing angles.
Motorized Floor-Rising Design: Retractable mechanism preserves living space aesthetics when not in use.
Zero Hotspotting: Even brightness distribution without common projection "hot spots".
Typical Usage Scenarios
- Living Room Home Theaters: Daylight-viewable entertainment without blackout curtains
- Conference Rooms & Corporate Settings: Professional presentations under standard office lighting
- High-End Boardrooms: Integrated with ceiling-mounted projectors for executive presentations
- Luxury Yachts & Smart Homes: Space-saving solutions with automated deployment
- Digital Art Installations: Gallery displays requiring ambient light tolerance
- Educational Institutions: Classroom projection systems with normal lighting conditions
