Spectroscopic Ellipsometer (& optional mapping stage)
- SE-R&D with motorized Auto-Focus for standard ellipsometry
- SE-SEMI with motorized Auto-Focus and X-Y motorized stages for increased measurement speed and accuracy
- DWE with dual laser wavelength for PV as a drastic improvement on SWE
- Thickness (Å): ±10 (Si)
Allied Scientific Pro from Taipei, Taiwan (R.O.C.), has teamed with a major testing equipment company to market their Spectroscopic Ellipsometers and Spectroscopic Reflectometers in both America and Europe. We offer three major models:
- SE-R&D with motorized Auto-Focus for standard ellipsometry
- SE-SEMI with motorized Auto-Focus and X-Y motorized stages for increased measurement speed and accuracy
- DWE with dual laser wavelength for PV as a drastic improvement on SWE.
All ellipsometers are equipped with state of the art software allowing remote connection from anywhere in the world. You can send us your sample for measurement and use the ellipsometer's software in your lab to verify the quality of both our hardware and software. You will be able to directly control the ellipsometer on your computer and also view the whole procedure via webcam live. Please contact us for more information.
Below are specifications and an experimental comparison of our SE-SEMI and a competitor's machine.

Sample Analysis for Customer
Earlier this year, a customer requested their own samples to be measured on two machines and the results compared. The first instrument is that of Company-S, one of our competitors, and the other is our own SE-SEMI. The results below demonstrate how the SE-SEMI obtained results normally within Angstroms of our competitors but at just a fraction of the price. Upon receiving these results, this customer purchased our ellipsometer. We will be more than willing to perform the same service for your laboratory free of charge.
