Silicone Diffusers

Fusion Optix Silicone Diffusers (including their PET-SIL films, diffusion domes, and molded secondary optics) are engineered for demanding LED applications that require extreme thermal stability, long-term durability, and precise light management.

By utilizing optical-grade silicone, these diffusers overcome the physical limitations of traditional plastics like acrylic or polycarbonate. They are designed to withstand high-output LED heat and intense UV exposure without degrading, making them the industry standard for high-performance architectural, industrial, and outdoor fixtures.

Key Features & Benefits

• Exceptional Thermal & UV Stability: Capable of withstanding continuous operating temperatures from -40°C to 130°C. Optical silicone is inherently resistant to UV radiation, completely eliminating the yellowing, cracking, or color-shifting common in plastic diffusers over time.
• MicroTEK™ Diffusion Technology: Leverages proprietary volumetric diffusion particles to achieve maximum light scattering with minimal insertion loss. This delivers perfect luminance uniformity, excellent color mixing, and eliminates LED hot-spotting while maintaining ultra-high optical efficiency.
• Flexible Form Factors: Available in a diverse range of formats—from high-temperature silicone-on-PET films (PET-SIL) provided in custom rolls, to molded 3D diffusion domes, drop lenses, and flexible linear optics that easily snap or slide into aluminum profiles.
• ColorSure™ Lifetime Performance: Integrated with patented color-stabilization technology to ensure that the color temperature (CCT) and color rendering (CRI) of the light source remain perfectly consistent throughout the lifespan of the fixture.
• Environmentally Rugged: Naturally resilient against moisture, chemical exposure, and mechanical impact, making them exceptionally reliable for harsh industrial environments, wet-location outdoor luminaires, and compact, high-power downlights.
