Welding and Arc Flash Dyes
Arc or flame cutting as well as welding operations produce potentially harmful ultraviolet, visible, and infrared radiation that can damage the human eye. For these operations, quality certified eye protection is required which reduces the intensity of the light. Epolin produces Epolight™ dye formulations and formulated ready to mold Luminate™ pellets that conform to the […]

Performance eyewear customers demand the highest visual acuity in addition to fundamental eye protection. Epolin has developed custom high contrast Epolight® dyes that eliminate visual “noise” and make colors “pop” for improved perception during competitive sports and leisure activities. Our dyes have demonstrated solubility, suitability and stability in impact resistant polycarbonate lenses and are available […]
Read MoreLaser Absorbing Compounds
Epolin can provide Epolight™ dyes or Luminate™ pellets that are designed for blocking specific laser wavelengths. We can meet the Absorbance or Optical Density requirements for one or more laser wavelengths while maximizing the Visible Light Transmittance of your thermoplastic lens or window. The table below provides examples of several of the laser compounds that […]

Visible Opaque Infrared Transmitting Dyes for Thermoplastics Epolin’s Epolight™ Visible Opaque, Infra-Red Transmitting (VOIRT) dyes for thermoplastics produce visually opaque to semi-opaque (grey or colored) filters while transmitting infrared signals or information. VOIRT filters can be customized to optimize transmission or reduce noise in 720nm -1050nm wavelengths and beyond. Typical applications include digital electronics such […]
Read MoreABSORBANCE – TRANSMITTANCE CONVERTER
A = 2 – log10 %T A spectrophotometer measures light transmittance through a material and from that absorbance can be inferred. Transmittance and absorbance have a logarithmic relationship. For example, a material transmitting 0.0001% would have an absorbance (optical density) of 6. Use the tool below to easily convert between absorbance and transmittance. Convert Transmittance […]
