Micro Prism Control (MPC) Product Information

Microstructured acrylic for light-management

Product

The Micro Prism Control (MPC) provides outstanding de-glaring performance. The prisms are designed as cones which provide exclusive geometric features optimized with numerical algorithms. The key features of CDP are high efficiency, smooth de-glaring characteristics, and an opal appearance.

Properties

  • High transparency microstructured prism sheet
  • Unique and homogenous glare reduction
  • Highest possible efficiency
  • Smooth de-glaring properties
  • Suppresses high-angle light above 65° to reduce visual glare while increasing on-axis light (“gain”)
  • Enables luminaires to comply with EN12464 glare specifications

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.
