Solatube International Inc.’s OptiView light-shaping diffusers are lenses oriented to guide daylight without glare, aberrations or flash. The light diffusers have a frost-like appearance and micro-replicated lens technology with pseudo-randomized lens orientations that guides daylight and delivers diffused daylight. OptiView Wide is used for horizontal, ambient illumination and/or wall washing lighting. OptiView Superwide has high-angle illumination and is used for wall washing and volumetric daylighting. OptiView Narrow is used for highlighting specific objects in a space and for creating pools of high illuminance. LED lighting kits are optional and assemblies (dome, flashing, tubing, diffuser) have seals to prevent insect and dirt infiltration.
