| Sunlight that is scattered from air molecules, dust and water vapor and comes from the sky vault.
|
| Transmitted light that is scattered evenly in all directions as it passes through a material.
|
| Certain hardwoods in which the pores tend to be uniform in size and distribution throughout each annual ring or to decrease in size slightly and gradually toward the outer border of the ring.

| See Suction Diffuser.
|
| 1. A device for distributing air in a forced air heating/cooling system; often flush-mounted on a ceiling, it has slats to direct the conditioned air evenly into the room or space; components of the ventilation system that distribute and diffuse air to promote air circulation in the occupied space. 2. A lens in a light fixture to diffuse light.
