Silicone Optics

POL can now provide advanced optical product design and rapid manufacture in the latest silicone resins to gain design and cost advantages in our customers’ applications.

The properties of optical silicone resins can be fully applied in POL’s opto-mechanical design capabilities, providing optimised optical performance, reduced part count and lower overall  product costs.


The advantages of optical silicone resins are:


  • Excellent transparency giving high light transport efficiency
  • No yellowing under high temperatures and prolonged high UV exposure
  • High colour and mechanical stability gives prolonged product life


  • Flexible resins giving high impact resistance
  • Thick and thin component sections can be moulded accurately with no sinks
  • Flexibility of the resin allows undercuts to be accommodated in the part design
  • Seals can be moulded into the optic, reducing need for secondary sealing on assemblies
  • Optics have intrinsic vibration dampening and shock resistance
  • Minimal compression set under deformation loads
  • Enables over-moulding onto light sources and other components
  • Hardness – 70 Shore A and other hardnesses available for specialist applications


  • High thermal resistance from -40°C  to 150°C
  • High chemical resistance



Standard Silicone UV Optics:

POL has now developed standard optical solutions for high power UV LEDs for applications such as:

  • UV curing of adhesives
  • UV curing of printing inks and lacquers
  • Indoor and outdoor UV decorative lighting
  • Water sterilisation
  • Microscopy illumination
  • Currency inspection
  • Forensic analysis
  • Non-destructive testing
  • Detection of fluorescent minerals

Design and Development

The latest computer optical design and ray trace programs with optomechanical innovation are used to take full advantage of plastics materials. Complex optical surfaces combined with integral low cost assembly features.



SLA (Stereolithography), SLS (Selective Laser Sintering), Clear SLA, SLA to Vacuum Casting, Direct Machining and Tooling options.



Proven optical quality toolmakers are chosen and assisted by mould flow analysis to optimize the tool. Our specialist toolmakers are skilled in optical surface generation and polishing.


Global Manufacturing

Our moulders are trained in the art of optical moulding. Mould flow process analysis and thorough F.M.E.A. is controlled by the Project Manager to ensure quality and quantity.


Technical Development

Our integrated approach to design enables optical components to become part of the total solution, including how they interface with the other non-optical components.


Optical Coatings and Films

Plastics optical components can be coated in poly-siloxane and acrylate based resin blends to impart more robust properties.


Project Management

Every project has a dedicated Manager to ensure as tasks are actioned, the client is kept informed on progress at each stage. Timing plans are used to monitor progress against agreed milestones and they ensure full control through-out the design, tooling, sampling and production stages.
