Non-contact profilometer for large areas
available with a variety of sensors

OverviewApplication examples
Key features

Fast and accurate measurement

Using a chromatic white light sensor for quickly scanning large areas. Also available with confocal microscope or 3D white light interferometer.

Sophisticated software

The system software SCAN SUITE combines SCAN CT for individual measurements and data analysis with the automation module ASCAN. Based on the latest programming technologies the system control, data collection and analysis are combined in an operator friendly user interface.

Scanning of large areas

The surface measurement system includes a highly precise linear axis with 315 mm travel in x-, y-direction.

User friendly design

The combination of fully integrated software and hardware is designed to make it easy and fast to obtain accurate and repeatable results.

Overview

The CT 300 is a non-contact profilometer with a 315 mm x-, y-motion system. It can handle up 12” wafers or other large substrates and parts.

Using a chromatic white light sensor and a data collection rate of up to 20 kHz the inspection time is minimized. The confocal microscope and 3D white light interferometer sensors offer unmatched resolution in z-direction down to 0.1 nm. With our multi-sensor technology several sensor heads can be mounted simultaneously including infrared interferometers for measureing wafer thickness.
