How to Clean an Anti-Reflective Coated Substrate

June 18, 2013

One of the most commonly asked questions we get here at North American Coating Laboratories is “how do we clean an anti-reflective coated part once we receive it?” This question is especially important in the high-end precision optics realm, as small particulate on top of a coated surface can disrupt numerous optical systems that operate behind the coated substrate. The reason anti-reflective coatings are difficult to clean is due to their “peak and valley” microstructure that is a catalyst for destructive interference of light. In general terms an anti-reflective coating is a series of dielectric layers with varying refractive indices…

ITO Coating on Plastic

June 18, 2013

As the consumer electronic market evolves manufacturers and industrial designers are looking for new and better ways to increase the performance of their devices while also making them thinner, lighter, and less expensive. One of the fastest growing approaches in the optical display industry to this trend is addressing display substrates with polymers coated with transparent conductive material or Indium Tin Oxide. Indium Tin Oxide is a transparent conductive oxide that is deposited on to clear display substrates in order to increase their conductivity. Applying a clear conductive coating to display substrates is mandatory in numerous applications. Among the most…

What’s the Difference Between Anti-Reflective and Anti-Glare?

February 7, 2013

A common question we receive here at North American Coating Laboratories is “what is the difference between an anti-glare process and an anti-reflective process?” The answer isn’t completely straight-forward, but once we discuss your application in further detail it’s usually easy to determine which process and treatment will be most suitable for your project. The basic difference between anti-reflective coatings and anti-glare treatments is the capacity at which they diffuse or eliminate waves of light in all spectrums from UV to long-wave infrared. Anti-glare solutions utilize diffusive properties to fragment the reflected light off the surface. Diffusion works by reducing…
