New Alpha-SE options

We now offer a complete range of accessories for our low-cost spectral ellipsometer Alpha-SE:

Liquid cell

For measurements in liquid ambients. The cell has a capacity of 500 µl and can be used with both glass slides and 1″ or 2″ wafers.

Transmission mount

To allow vertical mounting of samples for transmission measurements.

Manual translation

Allows manual xy-positioning of the sample over a 12 mm range with 0.025 mm resolution (micrometer screw).

Focusing option

Easy-to-install focusing lenses reduce the measurement spot size to < 500 µm.

Camera

Even small sample structures can be viewed with the camera image integrated within the CompleteEASE software and the beam measurement spot can be located.
