Bte Born GmbH

We set new standards in Optical Coatings

We set new standards in optical coatings through our commitment to innovation, quality, and customer satisfaction. With our cutting-edge technologies, extensive expertise, and dedication to pushing the boundaries of what's possible, we continuously strive to exceed expectations and establish new benchmarks in the field. Our relentless pursuit of excellence ensures that we consistently deliver superior coating solutions that meet the evolving needs of our customers and the industry as a whole.

We employ state-of-the-art vacuum evaporation and sputtering technology at Bte Bedampfungstechnik GmbH and Born Coating GmbH, both specialising in optical coatings and located in Elsoff/Westerwald (Rhineland-Palatinate). Born Coating GmbH, a subsidiary, focuses specifically on automotive applications (IATF 16949:2016) within this domain.

As manufacturers and developers, we bring sophisticated coating solutions to life for technical components. Since 1992, we have been recognised as one of the most innovative companies in vacuum coating, earning the trust of customers across various industries. Our lean organization, flat hierarchies, efficient resource utilisation, and service-oriented business processes render us highly flexible.

Currently equipped with 28 vacuum coating systems, along with patented and certified processes, we are adept at meeting the demands of new large-scale productions with rapidly increasing requirements. Our success is attributed to our dedicated staff, whose extensive experience contributes to the development of new thin-film processes and manufacturing methods.

In-depth consultation, coating design, and the development of novel coating solutions constitute our core competencies. With our expertise, we are the preferred partner for a wide array of optical coatings.

We employ state-of-the-art vacuum vapour deposition systems and sputter coating technology!

Coatings using PVD (electron beam) and sputtering systems:

  • Electron Beam Evaporation (EBE)
  • Ion assisted deposition (IAD) 
  • Advanced Plasma Source (APS) 
  • Sputter process/sputtering system
  • High-vacuum coating systems with planetary system 
  • Coatings in the spectral range from 200 nm to 2500 nm

Various post-treatment processes complete our range of services:

  • Laser cutting of glass and layer ablation
  • Cutting by means of scribe & break
  • Glass processing
  • Lamination of optically active films on glass (polariser, phase retarder)

Quality Management

Quality is paramount in coating processes. High-quality coatings are essential for ensuring the long-term functionality and reliability of coated components. They not only enhance the performance of the products but also contribute to the overall efficiency of production processes downstream.

We guarantee you the highest quality and environmental standards through:

  • Continuous improvement processes (CIP)
  • FMEA system (Failure Mode and Effects Analysis) for evaluating, analysing, and minimising or eliminating errors as early as the process planning phase
  • Process and planning reliability with the help of state-of-the-art methods for product and process monitoring
  • Safety through compliance
  • Quality management (QM)
  • Speed and flexibility thanks to value stream optimised processes
  • Conservation of resources and the environment thanks to appropriate production technologies (recycling, utilisation of process/waste heat, use of our own photovoltaic systems)
  • Sustainable energy management to optimise the use of all resources


Depending on requirements and customer wishes, we offer a range of measurements and testing options:
