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.
