The XY motorized stage provides automated stage movement for sample mapping. Additional features such as CCD camera monitoring and pattern recognition software combined with the integrated microspot optics delivers the ideal solution for accurate characterization of patterned wafers.

The rotation or q stage allows the automated 360° rotation of the sample, and is useful for characterization of complex anisotropic samples and liquid crystals.

The temperature controlled stage allows sample characterization at a range of temperatures (from -196°C to 600°C) for the investigation of new material properties (thermal transition analysis for polymers, band structure for compound alloys).

The automatic goniometer provides automated variable angle measurements. The purpose of multiple angle acquisition is to increase the amount of data available for characterizing a material. Additionally, each material exhibits a Brewster angle that provides more sensitivity than others.

Optical access to the sample is made via 3 fused silica windows. Two of the windows are mounted at 70º to normal for ellipsometry access, and the third port allows the user to observe the sample inside the cell. The cell body that comes into contact with the sample is manufactured from PVC, and the sample holder is manufactured from PTFE to avoid any interaction with the medium.

The cell volume is 43 ml, and comprises an Ag/AgCl reference electrode and a platinum counter electrode. Electrical contacts are provided by robust, high integrity feedthroughs.

The liquid cell consists of a 30mm (L) x 30mm (W) x13mm (H) cuvette made of stainless steel, Teflon or PEEK polymer. It comprises two fused UV silica windows mounted at 70° allowing the light to pass through for the investigation of solid/liquid interfaces. It supports samples up to 4 mm thick and requires 12 ml of liquid for solid/liquid experiments.
The choice of materials and the design of the cell allows complete disassembly so that the cell can be thoroughly cleaned, eliminating cross contamination when it is used for different experiments.
