Product Information

J.A. Woollam within a user-friendly interface. Real-time ellipsometry data contains a wealth of information. Samples can be fully characterized before, during,

The oscillators described mathematically in the Gen-Osc layer represent the dipole response of the material and can be used to describe comparable physical parameters, such as band gap.

Every Woollam ellipsometer system includes a compensator to manipulate the polarization state. For the VASE and VUV-VASE, this involves our patented AutoRetarder before the sample. For the M-2000, alpha-SE, and IR-VASE we incorporate rotating compensator technology. There are many advantages to using compensators in an ellipsometer design, including: The General Oscillator layer, or Gen-Osc, was developed to simplify the modeling of material optical constants. The Gen-Osc layer models the dielectric function of a material as a linear summation of wavelength-dependent oscillators. The group's formation - joining other local action groups like ARCH and Garston Futures - has been specifically inspired by a number of recent plans for the area focussed around heavy industry and the processing of chemicals and waste.

This tutorial provided by the J. A. Woollam Co. is an introduction to ellipsometry for anyone interested in learning more about ellipsometry and its applications. This tutorial is written with the novice in mind, but experienced ellipsometry users will also benefit from the information presented in this discussion.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 We offer a variety of sample stage mounts to accommodate your measurement needs. Our standard and small sample stages are provided with every ellipsometer, while the others are available as upgrades. Options include: CompleteEASE enables easy visualization of ellipsometry data acquired as a function of time and allows users to easily select individual time slices to view and compare. The AutoRetarder is a computer controlled MgF 2 Berek waveplate (compensator) used to accurately introduce retardance into the beam path. Because the compensator is under computer control, it is possible to generate appropriate retardance values (0 – 90°) over a broad (140 – 2500 nm) spectral range. The retardance is automatically adjusted to give the highest measurement accuracy for any sample.
