ARC broadband anti-reflection coatings effectively reduce reflections and provide a clear, color-neutral view. The 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 interference-optical ARC 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.
Uncoated optical surfaces can cause ghosting, which is the appearance of a weak, reflected image superimposed on a transmitted image, resulting in decreased sharpness and a blurred image. Our anti-reflection coating (ARC) effectively minimizes these unwanted reflections, resulting in sharper, brighter, and higher contrast images. A secondary laser beam is also generated when a laser is projected through an optical element if the surfaces do not have an anti-reflective coating. Our ARC effectively suppresses all 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 uncoated reflective surfaces. 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 ARC-B coatings, we use selected extra-clear BOROFLOAT®. In all cases, the coatings are matched to the refractive index of the substrate material for best performance.
Our capabilities extend beyond the anti-reflection and anti-glare coatings described on this website. We can custom design and apply our coatings to optical lenses and other optics the customer provides. In addition, adapted anti-reflection layers for particular wavelength ranges or single wavelengths from VIS to IR are available on demand.
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. You can always order the exact sizes you need! Our strength is the fast fabrication of optics that fit your application perfectly.

If you want 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 precise 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 details and specifications given are mean reference values and are not guaranteed. Please consider our "Notes on Specifications".
