Weshalb bvTechCon?

Nutzen Sie unsere umfassende Erfahrung mit Entwicklung und Produktion von präzisionoptische Komponenten, mit der wir maßgeschneiderte funktionierende Lösungen anbieten können, abgestimmt auf Ihre Situation, auf Ihr Equipment, Ihre Fertigungsmöglichkeiten und Ihr Budget. Wir respektieren Kundeneigene Produktentwicklungen in höchstem Maße, und erkennen die Empfindlichkeit der damit verbundenen technologische Informationen und Erkenntnisse. Es unsere tägliche Aufgabe, Verbesserungen in Kundenspezifische Konzepte zu finden und zu Implementieren. Wir helfen Produktionsschwankungen zu reduzieren oder zu eliminieren, um eine stabile und zuverlässige Produktion mit vorhersagbare Qualität und möglichst kurze Produktrealisierungs-Zyklen zu erreichen.

Spezifikationen

A specification of the desired properties is needed before we can start. If a suitable specification is missing we will assist you to make one. Sometimes (quit often) we find unrealistic specifications that need to be adjusted in order to get a produceable product. Unrealistic specifications can cause a series of nerve wrecking and costly experiments with never-converging results. This would lead to spiral of costly and efffordless attempts to find a suitabledesign, in troublesome process implementation and eventually to disappointed customers. Sometimes just an overkill of requirements to be on the safe site may cause unnecessary trouble. It is essential to 1st make specifications realistic before entering the design and implementation process.
Coating Design

Coating designs can be made by pushing a button. Todays software is capable of generating even complex multi layer stacks from scratch, by giving the required spectral requirements. This might give the impression that pushing a button is sufficient to get a decent and produceable coating design but fortunately for us, this is rarely true. Instead it needs good knowledge of optical properties, design options and process capabilities to make a reliably optical coating design. You probably want a stable production process, and you will not get it by pushing a button. Experience plays quite an important role in stable production.
Process Implementation

Initial coating designs are often based on the capabilities and known material properties of sngle layers in your coating machine involved. Further optimization is required to compensate for individual tooling factors of thin versus thick layers of the same material, for material depletion of your evaporation sources in the course of the deposition process.

Process Stabilization

A sequence of identical depositions will show the statistical position and spread of the spectral performance of your coating. In unoptimized systems the coating results may show undesired deviations from the ideal spectrum, leading to rejects. Adaptations to deposition settings, shape masks, may be required to to give maximum production yield. , apted in order to way that small variations amongst subsequent coatig runs will be adapted to your equipments individual tooling factors and material properties. In the optimum situation someone optimized the layer property distribution over the full product area of your substrate carrier by interactively optimizing deposition parameters and the shaping mask so that you can get 100% yield with full
