Used RUDOLPH FE IV #9134034 for sale

RUDOLPH FE IV is an ellipsometer, a device that measures the changing polarization state of a light beam as it reflects off or passes through a material. It is part of RUDOLPH family of ellipsometers, a series of advanced instruments that provide highly precise and reliable optical measurements. RUDOLPH FE-IV is a state-of-the-art ellipsometer from RUDOLPH Technologies of San Jose, California. The equipment measures both the change in polarization state of the incident light beam and the change in the structure of the material surface, enabling measurements of a variety of optical properties such as refractive index, birefringence, absorption, and film thickness. The unit is comprised of a rotating sample station, illumination system, detection unit, computer controller, and software. The rotating sample station allows for the precise orientation of optically-relevant characteristics of the sample's surface. The measurement light source irradiates the sample surface with a focused light beam and the detection machine captures the reflected light which is then analyzed. The illumination and detection tool includes a polarimeter, a device which measures the changes in light polarization as it reflects off the sample's surface. The computer controller contains the software, which is used to automate a measurement sequence and calculate the desired optical properties. The user enters data regarding the sample's surface structure, illumination angle, and other optical parameters to create a measurement profile. The software then searches for a set of conditions in which the intensity of the reflected light matches a predetermined value. Once these conditions are met, the software calculates the optical properties and the results are displayed on the screen. FE IV offers a variety of features that enhance its accuracy and provide reliable measurements. These include a light source stability monitoring asset, which monitors the incident light intensity and offers automatic compensation for minor intensity variations. The model also offers high precision laser alignment, ensuring accurate and repeatable measurement results. The user-friendly software makes it easy to set up and use the unit, with a user-friendly graphical user interface and automated measurement sequence. FE-IV is an ideal instrument for a variety of industries, from semiconductor and optical materials manufacturing to pharmaceuticals and cosmetics. It provides precise and reliable measurements in a wide variety of optical applications. The advanced features and high precision make it an excellent choice for researchers and production applications.
