Our Interferometer offer you the latest measuring technology for non-contact roughness and profile measurements. They record even microscopic structures, flatness and surface roughness precisely and reliably. Through the active use of optical technologies, you achieve the highest precision in surface analysis.

What is interferometry?

First, we will clarify that interferometry is an optical measurement method that uses the superposition of light waves. You actively compare a reference beam with a measurement beam to generate interference patterns. These patterns make it possible to precisely determine distances, height differences and surface defects.

• Non-contact measurement: Ideal for sensitive or soft samples.
• High resolution: Achieve measurements in the nanometer range.
• Fast data capture: Analyze large areas in the shortest possible time.

Applications of interferometers

You can also benefit from interferometry in various industries:

• Quality assurance in production:
  Use interferometers to check flatness and surface roughness in areas such as microelectronics, metalworking or optical components and to ensure the highest quality standards.

• Research & Development:
  Use interferometers in laboratories and institutes to perform material analyses and investigate signs of wear – even on fragile or very small samples.

• Medical and Biotechnology:
  Use interferometric methods to precisely characterize implants and medical tools. This way you can optimize durability and compatibility.

• Optical industry:
  When manufacturing lenses, mirrors or laser systems, check the reflection and transmission quality at the highest level.
