December 6, 2016 Stoughton, MA- The PhE101M Multi-Wavelength Ellipsometer is an ideal discrete wavelength ellipsometer for measuring the refractive index and thickness of single and multi-layer films at several wavelengths. It has the widest variable angle (10-90°>) which is adjustable in steps of 5°s, with an accuracy of 0.01° (As an option, the angle of incidence can be varied continuously).

The standard wavelength of the PHE101M ellipsometer is HeNe laser at 632.8nm. The wavelength can be selected by a combination of 543nm, 594nm, 612nm, 635nm to 1164nm. Infrared sources at 0.83, 1.31 and 1.52 μm are also available.

The PhE101 ellipsometer is very easy to use and can be equipped with our new laser alignment tool which greatly improves the ease of use and speed of operation when compared to conventional alignment method.

November 23, 2016 Stoughton, MA- The PhE104 Infrared Spectroscopic Ellipsometer can be operated over the wavelength range 400 - 4000 cm-1(2.5-25um). PhE-104 NS-IRSE infrared spectroscopic ellipsometer is a unique infrared spectroscopic ellipsometer instrument based on monochromator-dispersion. It features highest accuracy, precision and is more economical compared to FT-IR spectrometer. Infrared ellipsometry is a great new technology that proves invaluable to solid states and chemistry fields. It can be used on any substrate and offers high sensitivity on thin films down to surface passivation layers. Information on the optical constants,film thickness and chemical structures can be derived from the measurements.

November 14, 2016 Stoughton, MA- The PHE series professional software provides predefined and user defined patterns, auto return positioning and graphical display of the data maps. The step resolution is up to 0. 4 um. For single transparent films the homogeneity of the thickness and refractive index can be displayed graphically as a color-scale plot, a contour plot or a 3D plot. The wafer mapping option includes a precision x - y stage(50X50mm, 100X100mm, 150X150mm or 200X200mm) with computer controlled operation.

November 7, 2016 Stoughton, MA- The PHE-103 series elliposometer s a new model which adds the Transmission and Variable Angle Reflection function. This variable angle spectroscopic ellipsometer operating in the spectral range 250 - 1100nm or 250-1700nm or 250-2100nm. In the PHE-103 a broad band white light source is used to illuminate the sample spot. The layer stack imparts a change in state of polarization to the light and is reflected back through the analyzer and into the detector; where it is measured under the ellipsometric parameters of Psi and Delta. The spectral dependence of the refractive index, dielectric constants of the materials and other parameters under measurement are determined by comparing the measured data to a theoretical model, which defines the layer structure in detail.

October 27, 2016 Stoughton, MA- Ellipsometry is an optical technique for investigating the dielectric properties (complex refractive index or dielectric function) of thin films. Ellipsometer measures the change of polarization upon reflection or transmission and compares it to a model. It can be used to characterize composition, roughness, thickness (depth), crystalline nature, doping concentration, electrical conductivity and other material properties. It is very sensitive to the change in the optical response of incident radiation that interacts with the material being investigated. Handbook of Ellipsometry edited by ompkins, H.G. and Irene E.A. and Handbook of Optical Constants of Solids edited by Edward D. Pa have everything you ever wanted to know about ellipsometer. We recommended!!
