Our ARC broadband anti-reflection coatings effectively reduce reflection and provide a clear, color-neutral view. Fully dielectric, vacuum deposited AR coatings match the refractive index of the substrate material to the ambient air, minimizing the amount of reflected light and maximizing transmission performance. Any uncoated glass will reflect 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 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 over single layer anti-reflective coatings, which often still reflect up to 1-2 % or more. In addition, ghosting caused by the natural reflection of uncoated optical surfaces is undesirable. When ghosting occurs, a transmitted image is superimposed by a weak, identical reflected ghost image, resulting in degraded sharpness and blurred images. When a laser is projected through an optical element, a secondary laser beam is created if there is no anti-reflection coating. Our ARC anti-reflection coating effectively suppresses these unwanted secondary reflections. The transmitted image is sharper and brighter, with significantly improved contrast, and imaging accuracy is maintained. Similarly, our ARC anti-reflection coating can reduce secondary laser beams. Using our ARC coatings with lasers increases usable energy because almost the full power of the laser beam is transmitted and not partially reflected by an uncoated reflective surface. The anti-reflective coatings of our double-side coated ARC and single-sided coated ARC-1S materials are applied to selected high-quality iron-reduced glass. For ARC-B coatings, we use high-quality, extra-clear BOROFLOAT®.
Our capabilities extend beyond the anti-reflection and anti-glare coatings described on this website. We can apply our coatings to optical lenses and other optics provided by the customer. In addition, adapted anti-reflection layers for special wavelength ranges or single wavelengths from VIS to IR are available on demand.
How to get a quotation? 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 quickly as standard size components are typically shipped. You can always order the exact sizes you need! Our strength is the fast fabrication of optics that fit your application perfectly.

If you would like us to coat your uncoated lenses with our AR coatings, please provide us with the exact specifications. The refractive index of the lens material, the exact lens dimensions, the angle of incidence and the focal length are essential for calculations. We need to know these details to develop the correct coating. 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 produced in large quantities.
All given details and specifications are mean reference values and are not guaranteed. Please consider our "Notes on Specifications".
