dopa company profile

For almost 30 years, dopa has been developing and producing diamond tools, consumables and machines for the production of high precision components of all kinds of materials such as optical glass, crystals, ceramics, metals and special material.

Our dopa tools and technologies are designed to create precision optics and parts that meet highest requirements in clearance, flatness and parallelism.

In order to meet our high standards, we ensure the quality of our diamond tools and consumables from step one until the completion of each process. All our processes take place inhouse – from the production, finishing, grading and checks of each ingredient, to the execution of various production steps and last but not least the quality control. We test and advance our tools and consumables on various grinding and polishing machines.

Thanks to our depth of inhouse added value our customers benefit from short delivery times. This applies to a set of grinding wheels for double-sided machines as much as for generator tools for micro optics or diamond slurry for polishing special ceramics.

Our broad product portfolio has enabled us to gather comprehensive expertise around the production of precision plano optics. This led to the founding of a second division, our own optics production facility about 20 years ago. Here, we produce mainly laser optics and high precision components for the optics, semiconductor, medical technology, luxury watches and automobile industry, as well as aerospace from Germany and the whole world.

Likewise, dopa offers contract work to carry out customized processing of precision components provided by the client.

Our own machinery and plant engineering department develops and builds single- and double-sided grinding, lapping and polishing machines. Depending on the process we equip them with best fit auxiliaries, tooling and accessories.

We are your competent partner for customized product and process development. Our services range from the conduction of feasibility studies and prototype production to the mass production. If you wish to start your own production, we facilitate the implementation of the entire process or any of its components including process parameters, tools and machines – providing you turnkey solutions.

Lichtenberger Unternehmen des Jahres

Our principle: “Developing Efficiency!”

Our products and services enable our clients to make their processes more efficient and therefore save time and cost. We aim to continuously improve products and processes for our clients.

Why dopa

We understand our clients

Due to our unique combination of tools manufacturing and optics production we understand our clients’ needs and problems. We discuss tasks in detail and quickly come up with simple solutions.


Fast delivery

We even aim to further reduce delivery times during the extension of our product portfolio through various measures. Our depth of inhouse added value facilitates this as much as the use of IT and automation.
Our AEO status reduces time needed for custom checks meaning our products can be dispatched internationally on the day of completion. We aim to deliver:
standard tools within 2 weeks,
standard optics within 4 weeks.

Customized products

We customize our products according to your requirements – even for quantities as low as one item.

Modern machines

We produce various machines for grinding, lapping and polishing. In addition to our new machinery, such as polishing slurry systems and cascade filter systems, we can also provide you with refurbished machines.

Development and provision of turnkey solutions

dopa is not just a supplier of individual products. We are your partner for turnkey solutions, too.
Next to grinding tools, we can offer you corresponding coolants and lubricants including slurry aggregates and cascade filter systems, measurement systems, machinery as well as process descriptions.

dopa as extended work bench

If you are looking to outsource individual processes such as grinding or polishing works, we are able to provide this service as well.


Comprehensive consultation

With our comprehensive expertise in grinding and polishing we can advise you thoroughly and assist in finding the right solutions for your challenges.


Customized optimization

We optimize tools and processes according to your needs. We can either enhance existing technologies or carry out entire technology changeovers. New or optimized processes can be evaluated at the dopa premises, so that the implementation at your production site only takes place after your approval. As a result, the usually long and difficult implementation period of new technologies will be a lot more time and cost efficient.
