Zeta-20 – Brilliant 3D Optical Profiler for Analyzing Sample Surface Features

The Zeta-20 enables analysis and imaging of surface characteristics on all kinds of samples, namely low reflectivity to high reflectivity, smooth to rough and transparent to opaque based on the proprietary ZDot™ technology.

The Zeta-20 can be customized for specialized measurement requirements using the software and hardware options. Hardware installation is simple and features ease-of-use.

Key Features

The main features of the Zeta-20 are listed below:

  • ZDot™ innovative 3D imaging is the basic format used on KLA optical profilers. The ZDot™ technology combined with KLA’s transmissive and dark field illumination schemes as well a range of objectives allows the instrument to handle very tough surfaces.
  • The thin film thickness measurement option is based on ZFT reflectometry
  • Angstrom level vertical resolution is provided with the ZSI shearing interferometer
  • ZIC improved differential interference contrast imaging is ideal for nanometer level surface roughness
  • ZX5 vertical scanning interferometry is suitable for measuring nanometer heights over a large field of view

User Testimonials

We tried using our interferometer to profile an important transparent sample with low-contrast topopgraphy, but were unable to focus. With the Zeta-20 optical profiler, we were able to completely characterize the sample in a few minutes.

Dr. Antonio J. López, King Juan Carlos University Móstoles, Spain

We use our Zeta-20 nearly every day and rely on it for quick measurements and sample characterization. It suits our needs perfectly. We were especially impressed by KLA's willingness to customize. We had a unique need, and they jumped at the opportunity to make it work for us. We've also been impressed by the level of customer service we've received.
