Used RUDOLPH AUTO EL #293600520 for sale

RUDOLPH AUTO EL is an ellipsometer that is used to measure the optical properties of materials such as the thickness, index of refraction, extinction coefficient, and surface roughness of thin films. The instrument is used by professionals to characterize and measure the properties of dielectric and semiconductor thin films. It provides accurate and reliable measurements of these properties when applied to a wide range of samples. RUDOLPH AUTOEL contains an integrated light source, an auto-tracking goniometer, and a charge coupled device (CCD) camera to measure the degree of polarization of light that reflects off of the film surface. The optical components are aligned so that only the s-polarized light is detected. The CCD camera is connected to a data acquisition system and a computer. When the sample is placed in the goniometer, the light source is turned on and the intensity of the reflected light is varied as the sample is rotated. The CCD camera then takes images that capture the intensity of the light as the sample is rotated. The acquired data is analyzed with special software developed for the RUDOLF AUTO EL and this information is used to create a map of the optical properties of the film. AUTOEL is designed to provide highly accurate, repeatable measurements. It has a wide positioning range and high resolution which allows for improved accuracy of measurements when compared to traditional ellipsometers. It can be used to measure material properties such as the thickness, index of refraction, extinction coefficient, and surface roughness of ultra-thin films with an accuracy of 1nm. RUDOLPH AUTO EL is a powerful and reliable ellipsometer that is suitable for use in laboratories, research facilities, and manufacturing plants. It can be used to accurately measure and characterize the optical properties of materials and thin films. The instrument is lightweight and easy to install, making it an ideal choice for both industrial and academic applications.
