Our ARC broadband anti-reflection coatings effectively minimize reflections, ensuring a clear and color-neutral view. The fully dielectric, vacuum-deposited multilayer coating design allows for matching the refractive index of the substrate material to the refractive index of the ambient air, thereby minimizing the amount of reflected light and maximizing optical transmission. In comparison, uncoated glass reflects approximately 4.25% of the incident light per side. Consequently, elements within an optical system lacking an AR layer typically experience an average loss of approximately 8.5% by reflected light. Our interference optical ARC anti-reflection coating design allows reducing reflections in certain parts of the visible spectrum to less than 0.2%, marking a substantial performance improvement over single-layer anti-reflection coatings. These typically lose up to 1-2% or more per side by reflected light.
Uncoated surfaces in optical systems can lead to the appearance of ghost images. This phenomenon occurs when a second, weaker image is superimposed on top of the transmitted image, causing blurring and degradation of image quality. Our ARC anti-reflection coatings are engineered to minimize these undesirable secondary reflections, ensuring optimal sharpness, brightness, and contrast. A similar effect can occur when a laser beam is projected through an optical element without an anti-reflective coating. This results in a secondary laser beam. The ARC coatings effectively mitigate these undesirable secondary reflections, ensuring optimal performance and reliability in various applications. When used with lasers, our AR coatings improve energy transmission by transmitting nearly all of a laser beam's power instead of partially reflecting it. The layers of our double-sided ARC and single-sided ARC-1S coatings are coated on selected iron-reduced glass, which has low absorption and high surface quality. For ARC-B coatings, we use selected extra-clear BOROFLOAT®. Our capabilities extend beyond the anti-reflection coatings described on this website. We are equipped for the deposition of high-performance coatings, and we can apply them to optical lenses and other optics provided by the customer. Additionally, we offer customized anti-reflection coating layer designs for specific wavelength ranges spanning from the visible spectrum to the infrared.
How do I get a quote? Are there any standard sizes?
We quickly make and deliver optics in custom sizes. We quote, fabricate, and ship custom-sized parts with anti-reflection coating as fast as standard-sized components are typically shipped. This means that you can always order the exact sizes you need! We are experts at quickly making optics that are just the right fit for your needs.

To coat our AR coatings on your lenses supplied to us, we need to know the exact specifications. This includes the refractive index and properties of the lens material, precise lens dimensions, angle of incidence, beam diameter, clear aperture, and focal length. To ensure a smooth and efficient coating process, the lenses must be clean and free from any existing layers or substances that could potentially interfere with the deposition process. Please provide information about the material of your lenses, the maximum allowable residual reflection, the relevant wavelength range, and the light source with which the lenses will be used. Please note that such custom coatings can only be applied in production quantities.
All details and specifications given are mean reference values and are not guaranteed. Please consider our "Notes on Specifications".
