We are biotech & analytical instrumentation optics experts.
We do not try to be all things to all people – we focus on biotech and analytical instrumentation. Our engineers are delighted to work closely with your team to design the right filters to help you fully optimize your instrument's performance. Not only do we understand your application, but we routinely do optical ray tracing, run Monte Carlo simulations, perform stray-light analysis, and of course, craft sophisticated optical filter designs. Optical system design consultative services are available.

Selected Applications:

• Fluorescence Instrumentation

• Raman Spectroscopy

• Biomedical and Other Laser Systems

How do we do it? Semrock has brought together modern highly-stable ion-beam sputtering systems, proprietary deposition control technology, and unique in-house software tools for the first time for the biotech and analytical instrumentation market. The result is the densest, most robust, and highest-performance optical filters on the market today.
