For technical applications
High-quality filter coatings
What are your requirements for high-quality filter coatings? Particularly scratch-resistant? Highly resilient? Precise measurement results during use – no matter how complex your requirements are, our solution in the field of optical filter layers is just as efficient.
The precise filter layers selectively block or allow certain wavelengths of light. Depending on your requirements, the filter can either be a bandpass filter that only allows a specific wavelength range to pass through, or a blocking filter that blocks certain wavelengths. We will work with you to find the right and efficient solution in the field of filter layers. Let us advise you now!

Every prototype starts with an idea.
From the idea to series production.
From the idea to prototype production to the manufacture of spherical optics, high-precision flat optics, technical glass, or optical assemblies, we will find an efficient product solution for you.
Concept
No matter how challenging the task, we work with you to develop solutions tailored to your individual needs.
Design
Designing means developing the blueprint for a technical product in such a way that it can be manufactured. We have the relevant expertise and the necessary technical equipment to do this.
Production
Your product is manufactured in our production facility according to your individual specifications. Our many years of experience and modern machine and plant technology are a great advantage for you here.
Testing
All manufactured components undergo the necessary testing processes. The measurement results are documented accordingly.
Delivery
We deliver your components in standard packaging as well as in special packaging tailored to your specific requirements.
