Prismatic Lens
"Lenses" : A lens is a sheet of plastic (without holes) that fits in the frame of a
fluorescent fixture between the lamp and the room below, or a translucent plastic
piece (without holes)
that wraps around a non-recessed fluorescent fixture.
The most common lenses found in commercial buildings are "Prismatic" lenses.
This is the industry standard lighting diffuser found in just about every troffer and
surface mount
fixture. It combines the maximum efficiency and light spread with low cost for excellent
economy & performance.
R-20 3/16" (P12) square prisms in a 45 degree diagonal pattern
Acrylic - The industry standard. Crystal clear, and non-yellowing for a
bright appearance and long life. Available in various thicknesses from
.085" to .187" and sizes up to 4' x 8' sheets.
Polycarbonate - The only choice in vandal-prone and high abuse
areas. This heavy duty material can withstand high impacts 10x
better than Acrylic but is not as UV stable & willdiscolor with age.
Available in thicknesses from .125" to .187"up to 4' x 8' sheets.
Polystyrene - The lowest cost material to meet the
strictest budgets but will yellow and get brittle with
age and UV exposure.
