Effective Reduction of Light Reflections

ARC broadband anti-reflection coatings efficiently 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 transmissivity. Any uncoated glass will reflect approximately 4.25% of the incident light on each side due to the 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 anti-reflection coating can reduce reflections in some parts of the visible spectrum to less than 0.2%, a significant performance improvement over single-layer coatings, which often still reflect up to 1-2% or more.

 

Suppressed Ghosting for Greatly Improved Imaging Performance

Uncoated glass surfaces can cause ghosting, which is the appearance of a weak, reflected ghost image superimposed on a transmitted image, resulting in decreased sharpness and a blurry picture. Our ARC anti-reflection coating minimizes these unwanted reflections, resulting in sharper, brighter, and higher-contrast images. 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 by uncoated reflective surfaces. The anti-reflective coatings of our double-side-coated ARC and single-side-coated ARC-1S are deposited on selected HQ iron-reduced glass. For the ARC-B coatings, we use selected extra-clear BOROFLOAT®. In all cases, the coatings are matched to the refractive index of the substrate material to achieve optimum transmittance.

 

Tailored Solutions for Enhanced Performance Across Wavelengths

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 you provide. 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. 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.
