Micro-Structured Acrylic for Light-Management

Product

The special geometry of the perpendicular prisms in the Linear Prism 90° (LP90) provides an array of features including beam splitting, ray deflection, and total reflection of perpendicular incident light.

Properties

  • Highly transparent 90 degree micro-structured prism sheet
  • Highest possible efficiency

Applications

  • Total deflection of perpendicular light
  • Fade out of direct sunlight (sun protection)
  • One axis beam splitter in luminaires (batwing distribution)

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.
