We Are dopa
dopa – for now 25 years we are your competent and internationally established partner for the development and production of diamond tools , the design of whole production processes and a specialized contract manufacturer for high end flat optics made out of different materials like optical glass, sapphire, ceramic, fused silica etc.
At this we have specialized us on the processing of optical glass, special ceramics and crystals. Our tools distinguish themselves by the fact that they produce also at high stock removal rates very fine, homogenous and scratch free surfaces, which have nearly no sub surface damage. This leads in the following manufacturing steps to a decrease of generally minimum 35 % of your polishing time. Furthermore it raises your products quality and stabilizes remarkably your processes. With their low wear our tools enable you moreover to produce very flat parts.
We own in our Berlin test laboratory most different grinding and polishing machines plus a wide range of measurement instruments. On those machines, that depict the state of the art technology in multiple industries, we run machining trials under real production conditions and optimize the tools and processes already here so far, that they can be implemented in our customer’s production as a complete system.
Improving existing technologies or visualizing whole technology changes as for example from lapping with loose abrasive to fine grinding or from polishing with diamond slurry to super fine grinding can be shown here while considering all economical and technological aspects. Using this our customers can cut down the long, hard and cost intensive implementation of new technologies at their end to a minimum or save it fully. Furthermore they are able to react much faster to changing market needs while not interrupting their running production. To push your borders we gladly assist you with our funded knowledge in choosing and making the right tools for your application.
We are developing efficiency. Please contact us!

Established early 2011 FISBA Photonics GmbH is a subsidiary of FISBA OPTIK AG, a world leader in optical systems and components based in St. Gallen/Switzerland.
Located at the Science and Technology Park in Berlin-Adlershof the engineering team is fo-cused on the development of new cutting-edge laser light sources and optical microsystems. Main emphasis is placed to fiber coupled light sources in the visible light region.

InBeCon GmbH offers technical consulting and support for the design and the production of electro-technical components and modules. The emphasis of the extensive experience is in the fields of opto-electronics and microsystems technology e.g. in the adoption of micro-mechanics for the miniaturization of various components and assemblies.

We support your product development as well as optimization in close collaboration with all partners by modelling of the optics and multiphysics properties with FEM. InBeCon GmbH was assigned a “Certified Comsol Consultant” for such FEM simulations.

In the next step we consult about electronic packaging and assembly technology for the manufacturing of your products starting from sample manufacturing to volume production. Here we offer a 30-years experience with new production methods and the knowledge about the know-how of specialized foundry partners.

InBeCon GmbH supports you with the IP-management for the protection of your know-how e.g. for patent generation, patent assessment as well as patent defence.

The micro resist technology GmbH is a leading company in the development and production of innovative photoresists, polymers and photopolymers as well as complementary process chemicals for lithographic manufacturing processes in micro- and nanostructuring.
