Our ARC broadband anti-reflection coatings provide a clear, color-neutral view. The vacuum-deposited all-dielectric AR layers match the refractive index of the glass to the ambient air to dramatically minimize optical reflection and glare on the surfaces and maximize light transmission.

Each uncoated glass reflects about 4,25 % of the incident light per side because of the difference in refractive index between glass and the surrounding air. So, each element of an optical system without an AR coating causes a light loss of approximately 8,5 %. Our ARC multilayer anti-reflection coating reduces reflections in some parts of the visible spectrum to less than 0,2 %, a significant improvement compared to single-layer anti-reflection coatings, which often still reflect up to 1–2 % or more.

Also, ghosting caused by the natural reflections of glass surfaces is undesirable in optical systems. When ghosting occurs, a transmitted image is superimposed by a weak, identical, reflected ghost image, resulting in degraded sharpness and blurry imaging. Our ARC anti-reflection coating effectively suppresses these unwanted secondary reflections. The transmitted image is sharper and brighter, offers significantly improved contrast, and nearly complete imaging accuracy is maintained. In the same way, our ARC anti-reflection coating can reduce secondary laser beams. Using our ARC coatings with a laser increases the usable energy, as almost the entire laser beam is transmitted and not partially reflected by an uncoated reflective surface.

We coat the anti-reflection coatings of our double-side-coated ARC and single-side-coated ARC-1S materials on selected iron-reduced substrate materials with display quality. For the ARC-B coatings, we use premium-grade, extra-clear BOROFLOAT^®. Moreover, we always optimize the refractive index of the AR coating layers according to the substrate material's refractive index for the best performance.

Our capabilities extend beyond the anti-reflection coatings described on this website. We can apply our ARC coatings to optical lenses and other optics furnished by the customer. Furthermore, customized anti-reflection coating designs for different wavelength ranges or single wavelengths in the VIS to IR are available upon request.

 

How can I get an offer? Are there any fixed standard dimensions?

Our company produces and delivers coated optics in individual sizes quickly. Hence, we can quote, fabricate, and ship individually sized optical parts with anti-reflection coating as fast as off-the-shelf components with fixed dimensions are typically delivered. You can order the exact sizes you need at any time! Our strength is the fast, customized production of parts that fit perfectly into your application.

If you want us to coat your lenses with our ARC coatings, please provide us with the exact specifications. Specifying the lens material's refraction index, precise lens dimensions, angle of incidence, and focal length is essential. We need to know these details for the correct coating development. The provided lenses must be clean and free of any other coating layers. Please let us know the material your lenses are made of, the maximum allowed rest reflection, the relevant wavelength range, and the light source you want to use with the lenses. Please note that such customized coatings are only possible in production quantities.
