Surface metrology in medical technology
Complex measurement task? Our solution.
We offer you reliable measuring instruments. High-quality and flexible.
In medical technology and biotechnology, the most innovative materials and technologies are combined. The durability and safety of these medical technology products are often used as quality factors. Everything must be right here.
FRT's optical metrology systems measure roughness, film thickness, step heights or many other surface parameters. Switch now to the surface measuring instruments of the MicroProf® series.
In the following, we show you some measuring tasks for which we create metrological solutions together with our customers.
Measurement Task: Topography (Shape, Structure)
In this Metrology Capability Banner (MCB) you see a topography measurement in form and structure. In the middle you can see the implant of a human tooth with millimeter precision. On the right you see the measurement image of blood cells in the micrometre range.
Measuring task: Layer thickness, layer stack
Here you see a thin film and film stack measurement. In the middle you see the film thickness of a blood bag evaluated to the micrometer. On the right you can see the thickness variation of the blood bag along a profile.
Measuring task: Roughness and waviness measurement
In the MCB you can see a DIN/ISO-compliant roughness and waviness measurement. In the middle you see the 3D surface measurement of an artificial knee joint with a roughness Ra=14 nm. On the right, the roughness analysis of the medical tubing shows a value Ra=0.351 μm.
Measuring task: Angle measurement
On the right you can see a flank measurement. In the center is a dental drill with flank angle evaluation. On the right, the surface roughness and angle of a cannula is shown via area measurement.
Measurement task: Step height and step width
Here you can see a measurement of step height and width. In the center, a microfluidic is shown based on its topography. On the right you see a profile measurement along the blue line, including analysis of step heights, widths and flank angles.
