Silicone Optics

Optical

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

Environmental

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

Mechanical

• 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 the 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 hardness’ available for specialist applications

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
