J.A. Woollam RC2 Spectroscopic Ellipsometer

Ellipsometer with dual rotating compensator technology

The RC2 design builds on 25 years of experience. It combines the best features of previous models with innovative new technology: dual rotating compensators, achromatic compensator design, advanced light source and next-generation spectrometer design. The RC2 is a near-universal solution for the diverse applications of spectroscopic ellipsometry.

The RC2 is the first commercial spectroscopic ellipsometer to collect all 16 elements of the Mueller matrix. Mueller matrix SE allows characterisation of the most advanced samples and nanostructures.

FEATURES

BEST MEASUREMENT ACCURACY
Advanced measurement capabilities allow the best accuracy from fast CCD-based ellipsometry
DUAL ROTATING COMPENSATORS
Synchronous rotation of two compensators provides high accuracy, high speed, and complete Mueller-matrix measurements
ACHROMATIC COMPENSATOR DESIGN
New achromatic compensator design with optimised performance over a wide spectral range. *patent pending
WIDE SPECTRAL RANGE
Collect over 1000 wavelengths from the ultraviolet to the near infrared, all simultaneously
FAST MEASUREMENT SPEED
Synchronous operation of both compensators allows highly accurate data without waiting to “zone-average” over optical elements. Collect the entire spectrum (over 1000 wavelengths) simultaneously in a fraction of a second
ADVANCED DUAL LIGHT SOURCE
Dual light source for extended spectral range with computer control of beam intensity. Automatically optimise signal on any sample (low or high reflection)

OPTIONS

Add cell with optical windows for measurement through liquid ambient. Monitor the liquid/solid interface in real-time. Temperature-controlled options available.

Add heat stage or cryostat for variable temperature studies. Measure samples at low and elevated temperatures.

Allows flat mounting of thin plastic substrates.

Combine SE and QCM-D measurements to detect sub-monolayer changes in thickness and mass.

The Environment Cell is an optional accessory for the M-2000 and RC2 featuring a patented vapour-delivery system to create relative pressure environments using a wide variety of solvents. The Environment Cell operates under standard atmospheric conditions enabling quick setup and teardown of experiments.
