Custom development – when your system requires more than a standard solution

Our strength lies in the combination of in-depth system understanding in laser technology and thermoelectric temperature control with comprehensive knowledge in power electronics, measurement and control technology, embedded systems, FPGA design and software development.

On this basis, we work with you to develop customized control solutions – precisely tailored to your technical requirements, application and general conditions.

Instead of starting your own development with high risk, time and costs, with Meerstetter you benefit from modular, tried-and-tested electronic components that we adapt flexibly: be it in terms of function, size, interfaces, integration or cost optimization.

What our customers from high-tech industries say about us

"Recently I had yet another excellent experience with Meerstetter. On top of the first-class electronics they provide, their technical support is simply outstanding - very fast and professional! Recommend to anyone looking for Laser and TEC controllers."

5 star review
Adam Polak

"We bought some peltier controller, works as described, support was fast and helpful. Looking forward to buy from you next time. Thanks!"

5 star review
Róbert Vígh

"Their TEC controllers are quite compact and useful. I have been using a bulky benchtop TEC contoller but Meerstetter's small board can do exactly the same job (but much cheaper). The customer support is very responsive and helpful."
