Used RUDOLPH AUTO EL #293597944 for sale

RUDOLPH AUTO EL is an ellipsometer, which measures the properties of thin films. It can measure the thickness, refractive index and optical anisotropy of thin films, as well as substrate reflectance, surface roughness, and scattering ratios. RUDOLPH AUTOEL system is equipped with a laser source, a control and data acquisition computer, and a sample stage. The lasers emit a beam that is directed onto the sample surface. The reflected beam is then sent to the detector, which measures the data in both polarizations. This data can be used to calculate the optical properties of the sample. The data is collected using a two-axis stage, which enables the precise positioning of the sample on the ellipsometer. The sample is first coated with a thin metal film, which forms the base of the reflective stack. The metal film is then coated with further layers of materials, such as polymers, oils, and solids. By varying the thickness of each layer, the user can achieve a range of optical effects and tunable features in the reflective stack. AUTO EL includes a state-of-the-art optical analysis software. This software calculates the optical properties of the sample and displays the results as easy-to-read graphs on the computer screen. The user can perform a range of measurements, such as total reflection, ellipsometry measurements, Monte Carlo simulations, and polarized optical measurements. With AUTOEL, users can investigate the optical properties of materials and surfaces. By controlling the laser source and the sample stage, the user can configure parameters such as the angle of incidence, wavelength, and polarization. Thanks to its advanced software, the user can create custom measurements, study aberrations, and analyze different types of materials, such as nano-particles and monolayers. RUDOLPH AUTO EL is capable of providing accurate results when used with a range of materials and surfaces. It is an essential tool in research and industry and can be used to investigate the effects of various parameters on the optical properties of samples and surfaces. This can help scientists to develop new products and technologies that can be used in a variety of applications.
