Ultra-Fast Spectroscope Ellipsometry

ULVAC have taken ellipsometry to the next level with a unique snapshot technique for measurement. The UNECS range provides high speed, accurate and repeatable measurements in a compact and affordable form. UNECS ellipsometers measure as fast as 20ms per point. ULVAC's snapshot technology is also highly reliable and low maintenance, contain fewer moving or consumable parts than conventional systems.

Portable Ellipsometry

The UNECS Portable weighs only 2.2 kg, and has a compact form factor with integrated carry handle. For use on large or oversize samples, the ellipsometer's stage can be detached, allowing measurements to be taken directly on the sample's surface.

Measurement is ultra-fast, as low as 20ms per point. There are 2 supported spectral ranges, the standard 530nm to 750nm and a visible wavelength spectral range between 380nm to 760nm.

ULVAC's unique snapshot measurement technology is robust and reliable, and easy to maintain. The measurement system contains no moving parts, and only a single consumable part, the halogen bulb light source. This makes the UNECS Portable a dependable mobile solution in demanding environments.
