Optical manufacturing demands accuracy – from start to finish. Apre’s state-of-the-art interferometers do just that by improving quality while simplifying process control. Rely on our precision interferometry solutions for fast, accurate measurements of surfaces, substrates, prisms, flats, spheres, wedges, wavefronts, and more.
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.

Obsolete software, dead computer, failed components, and budget constraints can hinder your interferometer’s performance. Our refurbishing service updates interferometers to improve resolution, replace the laser, clean and re-align the optics, and so much more. If your budget doesn’t allow for a new system, Apre’s upgrades just make sense.
