Effective Reduction of Reflections with the ARC Series Broadband Anti-Reflection Coatings

The ARC broadband anti-reflection coatings effectively reduce reflections and provide a clear, color-neutral view. The fully dielectric, vacuum-deposited AR coating design matches the refractive index of the substrate material to the ambient air, minimizing the amount of reflected light and maximizing optical transmission. An uncoated glass reflects approximately 4.25% of the incident light on each side due to the described difference in refractive index between the glass and the surrounding air. Thus, each element of an optical system without an AR coating causes a light loss of typically about 8.5%. Our interference-optical anti-reflection coating can reduce reflections in some parts of the visible spectrum to less than 0.2%, a significant improvement over single-layer anti-reflective coatings, which often reflect up to 1-2% or more.

 

Suppressed Ghosting for Greatly Improved Image Quality

Uncoated optical surfaces can cause ghosting effects, which is the appearance of a weak second image superimposed on the transmitted image. This leads to reduced sharpness and a blurred image. Our ARC anti-reflection coating minimizes these unwanted secondary reflections, resulting in a sharper, brighter and higher-contrast imaging quality. Similar effects arise when a laser is projected through an optical element without an anti-reflective coating. A secondary laser beam is generated. The ARC effectively reduces nearly all these unwanted secondary reflections to a minimum.

 

Optimal Energy Transmission

Using our AR coatings with lasers increases usable energy because almost the full power of the laser beam is transmitted and not partially reflected. The anti-reflective coatings of our double-side-coated ARC and single-side-coated ARC-1S are deposited on selected high-quality iron-reduced glass. For the ARC-B coatings, we use selected extra-clear BOROFLOAT®.

 

Tailored Solutions for High Performance at Custom Wavelengths

Our capabilities extend beyond the anti-reflection and anti-glare coatings described on this website. We can custom design and apply our AR coatings to optical lenses and other optics provided by the customer. In addition, adapted anti-reflection layers for particular wavelength ranges or single wavelengths from VIS to IR are available on demand.

 

How do I get a quote? Are there any standard sizes?

Our company quickly manufactures and delivers optics in individual sizes. As a result, we can quote, fabricate, and ship custom-sized parts with anti-reflection coating as soon as standard-size components are typically shipped, so you can always order the exact sizes you need! Our strength is the fast fabrication of optics that fit your application perfectly.

Essential Requirements for a Customized
AR Coating on Lenses

If you want us to coat your uncoated lenses with our AR coatings, please provide us with the exact specifications. The refractive index and properties of the lens material, the precise lens dimensions, the angle of incidence, and the focal length are essential for calculations. The lenses must be clean and free of any other coating layers. Please let us know the material of your lenses, the maximum allowable residual reflection, the relevant wavelength range, and the light source you intend to use with the lenses. Please note that such customized coatings can only be applied in production quantities.
