Asymmetrical De-Glaring Prism (ADP) Product Information

Microstructured acrylic for light-management

Product

The Asymmetrical De-Glaring Prism (ADP) is a special application of the Linear De-glaring Prism (LDP). These prisms are asymmetrical with a one-sided perpendicular flank. Parallel light is deflected asymmetrically which enables directed illumination of objects and surfaces.

Properties

  • Highly transparent asymmetrical microstructured prism sheet
  • Asymmetrical prisms with a one-sided perpendicular flank
  • Parallel/collimated light is deflected at 20°

Applications

  • For lighting applications with UGR < 19
  • Ideal for illumination of workstations

Processing

The recommended fabrication methods for Jungbecker Optics are:

  • Circular saw cutting (edge polishing required in a 2nd step)
  • Laser cutting

It is important for the laser to have 360° suction, which means the air, smoke, and dust should be extracted from under and over the sheets.

Thermoforming

Jungbecker Optics can be thermoformed according to customer specifications, however there are limitations to the curvature that can be achieved. Please consult with Roehm if interested in forming a specific part.
