Used RUDOLPH AUTO EL III #9104444 for sale

RUDOLPH AUTO EL III is a high-precision ellipsometer designed to measure surface parameters for scientific research and industrial application. It operates on the principle of ellipsometry, which is the measurement of the polarization state of light that has been reflected from or transmitted through a material surface. The ellipsometer's primary function is to measure the change in state of polarization after the light interacts with the material's surface. RUDOLPH AUTOEL III includes an incident light source, polarization optics, an angle of incidence detector, and a detector/analyzer system with a sample-mounting stage. The incident light source emits unpolarized light that is passed through the polarization optics before being incident on the sample-mounting stage. The angle of incidence detector, in combination with a four-quadrant detector, measures the intensity of light reflected from the sample surface at multiple angles and at two states of polarization. The detector/analyzer system then produces analysis of the sample's surface parameters. With a tilt range of 0° to 90°, adjustable in 0.5° increments, AUTO EL III offers high accuracy ability, even in challenging applications. In addition to precise measurement of reflectance and radiometric color measurements, it is capable of measuring n-value (or refractive index) with an accuracy of 0.0001 and k-value (or extinction coefficient) with an accuracy of 0.01. The ellipsometer also has the ability to measure thin film thicknesses up to 10 microns, as well as light absorption, coating uniformity, substrate uniformity, and film characterizations. AUTOEL III is a full-featured sophisticated piece of research equipment that is ideal for many different applications. Its intuitive graphical user interface enables the user to create custom configurations and automate the measurements taken. Furthermore, the robust software package allows for data reduction, calculations, and data presentation with accurate and repeatable results. All of the measurements and reports can be easily stored for future reference. RUDOLPH AUTO EL III is a powerful and reliable tool that can help you obtain detailed information about your surfaces quickly and efficiently.
