OMIS High Gain Optical Microcrystalline Cinema Projection Screen
White Screen for Reduced RGB Speckling
Overview
Ultra-Low Speckle
3.5% ultra-low speckle contrast maximizes the brightness, contrast, and image uniformity of RGB lasers, ensuring accurate color reproduction
Wide Viewing Angle
Supports 160-degree viewing and wide-angle projection
Cleanable Surface
Anti-oil and Anti-stain: Resists permanent markers with an easy-to-clean finish. Resistant to common spills and fruit juice
No Solar Effect
Eliminates harsh specular reflections and dead zones to ensure highly uniform light distribution
High Screen Gain
2.2 gain optical-grade white screen
Anti-Ambient Light Interference
Ambient occlusion rate of 55%, effectively minimizing stray light interference
Stable Performance
Exceptionally long service life with zero yellowing over time
Technical Principles
Utilizing Stacked Multi-layer Microlens Array (MLA) technology and multi-stage particle reflection pathways, the screen effectively destabilizes laser coherence to suppress speckle at its source.
It achieves a precision-engineered synergy between high gain, speckle mitigation, luminance uniformity, and color fidelity.
Optical Micro-Mirror Array: Core Technology
1. Professional Optical Design:
Features micrometer-scale optical micro-mirror structures, engineered with precision optical modeling and ray-tracing simulations to accurately control beam shape and propagation paths. Widely applied in imaging and beam-shaping applications.
2. Precise Light-Field Control:
Utilizes a microlens array randomly distributed across a spherical reflective structure to enable controlled, continuous, uniform, and high-gain diffuse reflection, optimizing image quality and brightness consistency.
3. Complex Light-Field Manipulation:
Employs parallel micro-optical modulation to homogenize light beams for improved illumination uniformity and simultaneously enhances imaging performance through extended depth of field and higher resolution.
4. Mass-Scale Micro-Mirror Industrialization:
Mastered the design and mass production of large-for-mat optical films embedded with ultra-high-density microlens arrays. A proprietary manufacturing ecosystem, supported by in-house developed equipment, ensures a closed-loop, end-to-end production capability.
