Background

Ellipsometry is a well-known non-destructive optical method for determining film thickness and optical properties. Imaging Ellipsometry combines the power of ellipsometry with microscopy and overcomes the limits of classical ellipsometers.

Imaging Ellipsometers

The Accurion Imaging Ellipsometers enable you to study the surface in three steps:

  • Generating high contrast image from the surface
  • Ellipsometry with highest lateral resolution (1µm)
  • Generating of 3D thickness maps

Surface Analysis

Accurion Imaging Ellipsometers operate on the principle of classical null ellipsometry and real-time ellipsometric contrast imaging. It has been utilized in surface analysis for more than 6 years and has a unique lateral resolution of 1 µm.

Scanning Probe Ellipsometric Microscope (SPEM)

Lateral structures less than 1 µm can be studied with the Accurion Scanning Probe Ellipsometric Microscope (SPEM). SPEM is a combination of the Imaging Ellipsometer with a Scanning Probe Microscope.

Ellipsometry Platform EP³

Ellipsometry Platform EP³ is the modular solution for Imaging Ellipsometry with modules for large area measurements and spectroscopic measurements.
