A.L.P. Lenses and Diffusers

ALP-1-CRACKED ICE The unusual UV stabilized polystyrene "cracked ice" pattern is an imaginative use of plastic panels, providing a sparkling crystal overhead effect. Non-linear in appearance, the asymmetric pattern provides complete lamp obscuration even in the shallowest plenum.

ALP-12/120-FEMALE CONICAL PRISMATIC LENS This quality extruded acrylic or UV stabilized polystyrene lens provides very good low brightness control with excellent light output. The lens utilizes a diagonally oriented prism pattern with square inversed prisms that are optically designed to provide excellent light control. The ALP-12/120 pattern has become a standard in the industry, offering economy with quality. Under normal interior conditions these panels will perform satisfactorily for 20 years.

ALP-15-FEMALE CONICAL PRISMATIC LENS The ALP-15 is an extruded acrylic lens with a large 3/8" square pattern design that renders a bold, well ordered look that hides the lamps from direct view. The recessed female conical pattern provides maximum strength to weight ratios for oversized areas up to 48" square. The lens is an ideal prismatic lens where the bolder prism pattern is desired.

ALP-19-MALE CONICAL PRISMATIC LENS This is the finest in extruded acrylic lenses offering superior lamp obscuration and excellent source brightness control. The small square base male prisms are organized in a parallel pattern providing a discrete and tailored appearance. The ALP-19 lens offers the crisp appearance and the optical preciseness often associated with injection molded lenses with the economies of the extruded lens.

ALP-23-FEMALE CONICAL CIRCULAR BASE PRISMS The ALP-23 acrylic lenses have female conical circular base prisms of 3/8" diameter running parallel and perpendicular to the length and width of the panel. The female arcuate pyramids form a network which provides maximum resistance to sagging. It is the most uniform and efficient prismatic lens currently in production for the lighting industry.

ALP-41-SECURITY-PRISMATIC LENS ALP 41 is utilized in areas where vandalism or damage may be a problem because it is virtually indestructible. This lens protects lighting fixtures by sonic welding a .187" clear polycarbonate panel and a .187” clear prismatic ALP 12 acrylic lens.

ALP-45-EGGCRATE PLASTIC LOUVER ALP 45 ( Eggcrate ) Plastic louver has long been an industry standard. This translucent louver provides a subtle luminous quality. Open cell design permits free air circulation.

ALP-52-FROST OVERLAY The ALP-52 is a shatterproof flat sheet with fiberglass reinforcement that is extremely resistant to breakage and vandalism. The acrylic contributes translucent elegance, color stability, and weatherability. Frost overlay diffusers are a good choice for flat lighting applications because they are break resistant and have less sag than ordinary acrylic diffusers.

ALP-SW-SMOOTH WHITE Smooth White Flat Sheet provides the greatest application potential in the lighting industry. These extruded smooth and crepe diffusing panels are available in acrylic or high impact light stable polystyrene, providing evenly illuminated lighting enclosures while reducing shadows and reflected glare.
