Metrology & Testing
At FISBA, we use state-of-the-art metrology and testing tools to measure the performance of complex, optical systems.
Verify Performance and Accuracy With Our Metrology and Testing Solutions
Measuring what we make is at the heart of what we do and is a core competency at FISBA. Metrology and testing solutions enable our team to deliver the highest quality products that meet our customers’ strict performance requirements.
Our engineering and precision assembly teams have a wealth of expertise and experience in the design and setup of metrology and test equipment. They use that expertise to characterize the optical performance of individual optics and complex lens assemblies and design and build custom metrology stations for miniature endoscopes commonly used in robotic surgery and minimally invasive surgery. The benefits of our approach to custom metrology enable real-time assembly feedback that correlates with the tolerance analysis performed in the design stage and can be used to validate as-built specifications.
Make Sure the Optics in Your Device Meet Performance Specifications
Our metrology and testing solutions provide peace of mind knowing the optics in your device are designed and built to meet performance expectations. Contact us today to learn more.
Precision Assembly Supported by Enhanced Metrology and Testing
Ensuring the precision, accuracy, and optimal performance of optical assembly components is a paramount focus for us at FISBA. We take pride in elevating quality assurance through regular optical metrology tests, establishing standardized and repeatable procedures that guarantee quality and instill confidence. Whether handling small batch or high-volume orders, our cutting-edge equipment ensures optimal results for all-optical geometries, showcasing the following capabilities:
- Measurement of aspherical and freeform surfaces with precision down to 50 nm
- Centering measurement accuracy of < 2 µm
- Exact evaluation of the imaging quality of our optics
- Determination of center thickness and air gaps with 1 µm accuracy
- Measurement of surface roughness with precision < 0.5 nm
