With a focus on superior product quality and value-added service, Beijing Scitlion has made Jebsen Industrial and Heraeus Quarzglas its key supplier for specialty fibre preforms, deepening its relationship with the two partners. 


Beijing Scitlion Technology is a high-quality ISO 9001:2008-certified manufacturer of optical crystals, fibres and devices, as well as specialty glass materials. It was established in 2013 to continue the 53-year legacy of Beijing Glass Research Institute (BGRI).


The Challenge: Sourcing Specialty Fibre Preforms of Consistent High Quality

Jebsen Industrial has a long-term relationship with Beijing Scitlion, supplying it and its predecessor BGRI with specialty fibre preforms from world-class supplier Heraeus Quarzglas for more than eight years. Beijing Scitlion uses the high-quality Heraeus preforms in its fibre drawing and coating processes and for the production of specialty glass. For several years, it had also been sourcing specialty fibre preforms from another supplier. Unfortunately, these preforms could no longer meet Beijing Scitlion’s high quality requirements.


The Solution: Highest Quality Product and Value-added Support

To assist Beijing Scitlion in investigating this quality issue and selecting the best solution for its needs, Jebsen Industrial provided professional consultancy and in-depth technical support since year 2013.



In-depth Investigation

The first step was to thoroughly examine the non-Heraeus preforms to determine where they were deficient and to demonstrate their quality shortcomings to Beijing Scitlion.


The Jebsen Industrial team paid several visits to Beijing Scitlion executives to present technical information, share market insight, and provide rapid feedback to questions and concerns. Jebsen Industrial also arranged for experts from Heraeus to accompany the team on three occasions to provide detailed technical support and first-hand market knowledge.


“This close face-to-face contact ensured that Jebsen Industrial understood Beijing Scitlion’s current challenges and future plans. We were then able to add value not just by offering a high-quality product, but by drawing on our close relationship with Heraeus to provide professional consultancy and expert after-sales support,” said Mr. Anson Yang, General Manager of Engineering & Technology Division, Jebsen Industrial.


Direct Comparison

Jebsen Industrial was able to provide Beijing Scitlion with a side-by-side comparison of the specialty fibre preforms from Heraeus Quarzglas and the other supplier. This clearly demonstrated how the Heraeus product could overcome Beijing Scitlion’s existing quality issues.


For example, with high-quality preforms, there is no photodarkening (or “photochromic damage”) inside the fibre, avoiding serious performance degradations and lifetime limitations in the finished product. Top-quality preforms, like those produced by Heraeus, have no leaking in the application, lower attenuation, smaller laser spot and a higher transparent ratio. Furthermore, the Heraeus preforms can be supplied in non-standard square geometries to achieve more precise, efficient and uniform laser cutting with a square formed beam.


“In optical device manufacturing, the quality of the finished product is dependent on the quality of the specialty fibre preform used. This is the reason that Beijing Scitlion has such high quality standards and demands only the best from its suppliers,” Mr. Yang continued.


With an aim to source the highest quality preforms and receive the best value-added service, Beijing Scitlion ultimately decided to make Jebsen Industrial its largest preform supplier.


High-quality Heraeus specialty fibre preforms



Heraeus’ Fluosil® preforms are fused silica core step index multimode preforms. They are made using the Plasma Outside Deposition (POD) process, which enables the creation of a highly fluorine doped cladding with a depressed index compared to fused silica. Fluosil® preforms are customized according to the properties of the core material used, the thickness of the cladding, and the numerical aperture required. Customers can select from a broad range of complex customized fiber designs with multiple layer structures and special shapes.


Heraeus Quarzglas is the technology leader and materials specialist for the manufacture and processing of high-purity synthetic quartz glass. It is also a world leader in industrial precious metals, sensors, biomaterials and specialty lighting sources. Headquartered in Germany, Heraeus has been family-owned for more than 155 years. It currently holds more than 5,000 patents and has more than 350 research and development employees in 25 development centres around the world. In Greater China, Heraeus Quarzglas has partnered Jebsen Industrial since 1968.
