Fizeau and LUPI Interferometers

Fast, Accurate Surface and Wavefront Measurements

Optical Metrology Instruments That Boost ROI

There’s no room for downtime or inaccuracies when it comes to optical manufacturing. Interferometers with low imaging resolution and obsolete software cut into profits and damage your reputation by sacrificing time and quality. 

Äpre interferometers – both standard and custom – improve your metrology capabilities so you can meet your customer’s demands. Choose from our S-Series interferometers and build the system that works for you.
