Prismatic Lenses

Unlike louvers with a specular finish which reflect light, lenses refract light. The direction of incident light changes as it passes through a lens. Although the majority of light is directed downward within a given distribution, a portion of the light is refracted into the higher angles.

Prismatic Lenses will display more of the light source's brightness than specular parabolic louvers. This additional brightness will tend to brighten the ceiling and upper portions of adjacent walls. Prismatic Lenses are most appropriate when brightness and economy are desired and where visual tasks are not being compromised.

Prismatic Lenses are without a doubt the industry standard light control media. They provide unequalled economy and efficiency but provided only limited control of light distribution. For areas where brightness and a wide light distribution pattern are valued Prismatic Lenses or Eggcrate Louvers are an appropriate choice.
