Are your optical metrology systems giving you just enough? Today you’re marginally meeting standards. But what about tomorrow, next month, and next year, and that leading edge customer? Äpre interferometers – designed around YOUR needs – push past your current capabilities so you can deliver more. More accuracy and resolution, with better process control and reporting. And with faster cycle times for better ROI.
Take Control with Äpre.
Fizeau and LUPI interferometers go from measurement to report in <5 seconds. Highly accurate, repeatable, and traceable.
Spectrally Controlled Interferometers directly measure surfaces and angles in one setup, for an ROI of < 1 year.
REVEAL easily generates interferometer measurement reports that are precise and traceable.
Your application, your requirements, and your schedule. Partner with our experts to design and manufacture a robust, manufacturable interferometry system that includes:
• Optical Design
• Mechanical Design
• Stages, Fixtures, and Accessories
Not sure where to start? We can work from scratch or begin with a file from our library of proprietary designs. No matter where you begin, you’ll end up with a system custom-tailored for you.
