cellular nature of parabolic louvers physically blocks the
passage of light at angles above the shielding angle. The
Specular aspect of the finish on the curved vertical surfaces
reflect down at angles equal to or less than the shielding
angle. When these louvers are viewed at angles beyond that
shielding angle, they will have little of the brightness
associated with the light source. The amount of brightness
depends directly upon the percent of Specular reflectance from
advantage of Parabolic Louvers is the high degree of
controlled light distribution that they offer. This precise
light control makes Parabolic Louvers ideal for areas with
moderate to high concentrations of computer terminals (CRTs).
This control is dependent upon the shielding angle offered by
the specific louver and degree of specularity of the finish.
Parabolic Louvers are the optimum choice for areas where
visual comfort and controlled reflection off of vertical
surfaces is critical.
