Used RUDOLPH FE IV #9412375 for sale

RUDOLPH FE IV is a cutting-edge, four-wavelength, prism-based spectroscopic ellipsometer designed to provide superior accuracy and precision in optical thin film measurements. This advanced instrument measures the change in light polarization as it travels through a sample and combines this with the angle of incidence to quantitatively measure the thickness and optical constants of the film. RUDOLPH FE-IV offers industry-leading accuracy and speed, and its unique design allows for a wide range of sampling where other instruments cannot measure due to their interfering with the light propagation. FE IV utilizes a proprietary optical design to couple the light efficiently into a single-mode fiber and optimizes the resolution of the intermediate stages for the highest accuracy. This system is the only commercially available ellipsometer on the market to use a quad cell system, which allows for independent measurement of four wavelengths simultaneously. The four wavelengths are 520 nm, 640 nm, 780 nm, and 830 nm. With a single scan of all four wavelengths, data acquisition is faster, with up to 1000 repeatable points achieved every 60 seconds. FE-IV detects changes in the optical path of a light beam as it passes through a light-sensitive sample. Using this data and combining it with angle of incidence, an accurate calculation of refractive index and film thickness can be made. The superior performance of RUDOLPH FE IV makes it a reliable tool in the analysis of sheet materials, membranes, biological cells and other complex media. RUDOLPH intuitive user interface is designed to ensure a smooth and efficient operation. The graphical user interface allows the researcher to develop advanced, detailed measurements, view data in real-time, set parameters for different measurements, and extract data for further analysis. RUDOLPH FE-IV also includes an advanced python scripting language which allows for easy automation of measurements. Overall, FE IV has rapidly become a trusted optical tool for scientists and researchers who demand accuracy and precision from their measurements. It is also a valuable asset for both production and research laboratories and processes, making it a highly desirable instrument for any optical thinner measurement.
