Beneq’s ALD equipment coupled with our long experience offers many possible applications of thin film coatings on various optical elements. Film uniformality, conformality and repeatability with the possibility of coating complex surfaces make ALD technology ideal for optical applications. ALD technology allows for precise control of film thickness which makes it optimal to use in optical coatings where films are required to be thicker.
ALD can be used to coat optics of any shape for anti-reflective coatings, reflective coatings and for other purposes. Contact us to hear more about coating possibilities for optics and photonics applications. Download optical coatings brochure.

Optical near-infrared filter on glass cylinder
Near-infrared (NIR) filters are typically several micrometers thick optical stacks of low and high index materials. It is not possible to coat such high quality filters on 3D surfaces, such as curved surfaces, using conventional PVD methods. Specifically Beneq's ALD technology allows for coating of thick layers with excellent quality.
Beneq’s customer, a supplier of CCD sensor based industrial vision systems, required their glass cylinders to be coated with a near-infrared filter.
The coating was done using a customized batch ALD process and using proprietary optical Al2O3 and TiO2 materials. Beneq’s robust production-tested equipment enabled a stable and reliable process for the challenging several micrometers thick film stack.
The customer utilized Beneq’s Development services to evaluate an optimal solution for their need and relied on our Coating Services for high-quality coating outcome. The glass cylinders were coated using the Beneq P400A batch coating equipment.
