High Current LED Lenses

Silicone Optics Lenses

Optical-grade silicones offer an exciting alternative for lighting manufacturers. Unlike glass and plastics, silicone:

Silicone Optics Lenses
  • does not age like polycarb, vinyl, or acrylic
  • does not yellow with time
  • does not craze due to heat, exhibiting no material
  • changes in temperature range from –115°C to 200°C
  • does not react to UV light
  • does not react with most harsh chemicals
  • offers high transmission across a broad spectrum, with 95% transmission or better from 365 nm (UV) to 2000nm (IR)

While silicone offers these material benefits compared to plastic molded lenses, it also offers advanced manufacturing benefits. For example:

Silicone Optics Lenses for Machine Vision Lighting
  • Silicone is very robust. It maintains its optical function over its lifetime and is resilient to changes in the environment.
  • Optical-grade silicones are capable of holding fine structure patterns and can possess reverse curves in a single molding tool; this cannot be done in conventional plastics.
  • Silicone’s ability to form complex optical elements using multiple shots in a single injection mold allows for a lower total cost solution for complex, multi-part optics.

Standard Lens Optics Available

Lenses for high current LEDsLight optics have been designed to give narrow and wide angle output with even illumination. Line optics are also available creating narrow thin beams of illumination. Working distances are as close as 100mm to over 6 meters depending on the lenses.
  • Narrow (Standard on all lights except ring lights) - Standard lenses create a narrow beam of illumination. Standard lenses can be used when long working distances are needed. Narrow are 12° angle cone lenses.
  • Wide - Wide lenses create a large area of illumination. Wide lenses can be used when short working distances are needed. Wide lenses create a flood light effect. Wide are 25° angle cone lenses
  • Line - Line lenses create a thin narrow bream of illumination. Line lenses create a line of light when used on L300 linear lights. Line lenses are 12° and 80° cone lenses.
  • Oval - Oval lenses create an elongated pattern of light. Oval are 12° angle cone lenses.
