XY motorized stage 

XY Motorized stage for Thin Film Uniformity Mapping

The XY motorized stage provides automated stage movement for sample mapping. Additional features such as CCD camera monitoring combined with the integrated microspot optics delivers the ideal solution for accurate characterization of patterned wafers.
In option for UVISEL and Smart SE
In standard for UVISEL 2 and Auto SE

Automatic goniometer 

Automatic Goniometer to Vary Angle of Incidence

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.
In option for UVISEL and Smart SE
In standard for UVISEL 2

Compact integrated goniometer 

Compact Integrated Goniometer for Cost-Effective Solution

The compact integrated goniometer provides a cost-effective solution for benchtop UVISEL and for benchtop UVISEL spectroscopic ellipsometer. This configuration is convenient for the majority of thin film applications.

  • Angle of incidence: 35°-90°, 5° step
  • Autocollimation system for sample alignment (in option)
  • Sample stage
  • Sample size: 200 mm
  • Sample thickness: max 20 mm
  • Manual Z height adjustment


Temperature controlled stage 

Temperature Controlled Stage to Study How Film Properties Change with Temperature

The temperature controlled stage allows sample characterization at a range of temperatures (from -196°C to 350°C and from Room temperature to 600°C) for the investigation of new material properties (thermal transition analysis for polymers, band structure for compound alloys).

Electrochemical cell 

Electrochemical Cell to Study Electrochemical Processes

The electrochemical cell has been designed by HORIBA Jobin Yvon for the study of electrochemical processes using UVISEL spectroscopic ellipsometer.

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.

Liquid cell 

Liquid Cell For Solid and Solid/Liquid Experiments

The liquid cell is designed to provide easy set-up and clean-up for any liquid and solid/liquid experiments using HORIBA Scientific spectroscopic ellipsometers.

The liquid cell consists of a 30mm (L) x 30mm (W) x13mm (H) cuvette made of stainless steel, 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.

Sealed cell 

Sealed Cell for the Characterization of Thin Films under Non-Air Ambient Conditions

The Sealed Cell has been designed for ellipsometric characterization of materials that are either sensitive to air or moisture or for experiments to study the effect of vapours / gases on material layers.
The Cell provides a completely sealed environment preventing ingress of air during measurement. A flow system is integrated with the design to allow introduction of gases or vapours into the cell. The sample is placed within the cell and the ellipsometer light beam passes through the two fused UV silica windows mounted at 60° on each side of the cell. A top window enables sample alignment. The Cell is manufactured from PTFE and all components of the cell can be easily removed and cleaned. The Cell is designed to mount samples of up to 50mm x 50mm, and allows translation of up to 10mm x 10mm for mapping purposes when the sample is placed inside.


Cryostat to Maintain low Cryogenic Temperatures

A cryostat option is available upon request, please contact us directly for more information.

Rotation or θ stages

Rotation Stage to Study Anisotropic Samples

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




  • 150 mm diameter
  • Resolution: 0.005°

Tilted Sample Stage 

Tilted Sample Stage For measurement of Photovoltaic Samples

The tilted sample stage integrates a 160 mm x 160 mm sample holder with vacuum chuck. Tilt adjustment from the horizontal position to 90° is ideal to optimize signal collection from textured Si photovoltaic samples, and the stage height is manually adjustable to allow samples of up to 10 mm thickness to be measured. The stage also allows transmission measurements.

Transmission cell

TTransmission cell for measurement of Sample Transmission and Ellipsometric Transmission at 70°

The tilted sample holder enables transmission measurements at 70° of small samples of 10mm to 50mm diameter and fits directly onto the standard sample stage used for HORIBA Scientific ellipsometers.

  • 2 measurements with and without sample
  • Transmission & ellipsometric transmission
  • Vacuum capability
  • Compatible with flexible substrate holder

Flexible Substrate Holder 

Flexible Substrate Holder For Convenient Mounting of Flexible Substrates

The flexible substrate holder allows rapid mounting of flexible samples into double rings for ellipsometric measurement. Two diameters are available 20 and 50 mm.
