Optical Diffuser Panel: Thickness 1-10 mm, Haze 70-95%

Component Specifications

Definition

An optical diffuser panel is a precision-engineered component designed to scatter and homogenize light from programmable lighting systems, creating uniform illumination by reducing glare, eliminating hotspots, and minimizing directional artifacts through controlled surface microstructures or embedded particles.

Working Principle

Operates on light scattering principles using surface microstructures (e.g., lenticular arrays, etched patterns) or volumetric diffusion (embedded particles) to redirect incident light rays through refraction, reflection, and diffraction, achieving Lambertian or controlled angular light distribution.

Materials

Typically made from optical-grade polymers (PMMA, polycarbonate, polystyrene), glass with anti-reflective coatings, or silicone-based composites; may include additives like barium sulfate or titanium dioxide particles for enhanced diffusion.
