The IR-VASE Mark II joins the chemical sensitivity of FTIR spectroscopy to spectroscopic ellipsometry across 1.7 to 30 microns. It gives n and k over the whole measured range without Kramers Kronig extrapolation, and needs no vacuum or reference sample, so liquid and solid interfaces can be studied.

The VUV-VASE measures from the vacuum ultraviolet to the near infrared and is used for optical characterisation of lithography thin films, high bandgap materials and immersion fluids. Placing the monochromator before the sample limits exposure of photosensitive materials during measurement.
The VASE is the established variable angle research ellipsometer, using a rotating analyser with the AutoRetarder and a custom scanning monochromator. A vertical sample mount supports reflection, transmission and scattering geometries on semiconductors, dielectrics, polymers, metals and multilayers.
The T-Solar is a photovoltaic measurement system designed specifically for textured samples. It is based on the established M-2000 rotating compensator spectroscopic ellipsometer and measures hundreds of wavelengths across the UV, visible and near infra-red. To cope with rough, textured surfaces that greatly reduce the reflected signal, it pairs a special high-intensity lamp source with an Intensity-Optimizer that adjusts the light source automatically to the ideal range for the sample. An adjustable tilt-rotation stage aligns the pyramid structures of alkaline-etched monocrystalline surfaces, which makes the system well suited to characterising AR coatings on etched silicon.
