Our ARC anti-reflective glass has dielectric optical coatings, providing a clear, color-neutral view. These vacuum-deposited AR layers match the refractive index of the glass to the ambient air, dramatically minimizing reflection and glare from the glass surfaces. The transmission in the visible range also increases significantly.

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, approximately 8,5 % of the energy gets lost through any uncoated glass element of an optical system. Our ARC anti-reflective glass reduces reflections in some parts of the visible spectrum to less than 0,2 %, a considerable improvement compared to simple single-layer anti-reflective or anti-glare glass, which often still reflects up to 1–2 %.

Also, ghosting caused by the natural reflections of glass surfaces is undesirable in optical systems. When ghosting occurs, a transmitted image is superimposed with a weak identical ghost image, resulting in degraded sharpness and blurry imaging. Our ARC anti-reflective glass effectively suppresses these unwanted secondary reflections. The transmitted image remains sharper and brighter and offers significantly improved contrast. The imaging accuracy is maintained, and nearly no light is lost. In the same way, our ARC anti-reflective glass can reduce secondary laser beams when used as a laser window. Using our ARC coatings increases the usable laser energy, as almost the entire laser beam is transmitted instead of being partially reflected by the glass.

We coat the anti-reflective coatings of our double-side-coated ARC and single-side-coated ARC-1S standard coatings to selected iron-reduced glass materials that meet display quality. We adjust the refractive index of the coating layers to the glass properties for the best performance. For the ARC-B series, we use premium-grade extra-clear borosilicate glass.

Our capabilities extend beyond the anti-reflective coated glass described on this website. We can apply our ARC to optical lenses and other glass parts the customer provides. Furthermore, a custom design for different wavelength ranges is available upon request.

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

Our company produces and delivers glass and optics of individual sizes quickly. We can quote, fabricate, and provide custom-sized optical parts as fast as off-the-shelf components with fixed dimensions can typically ship. You can order the exact sizes you need at any time! Our strength is the fast, customized production of glass parts that fit perfectly into your application.

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

All given details and specifications are mean reference values and are not guaranteed. Please consider our "Notes on specifications".
