Used RUDOLPH FTM #84752 for sale

RUDOLPH FTM is an advanced ellipsometer developed by RUDOLPH Research Analytical that is used to measure various parameters of thin films and surfaces. It is based on the ellipsometry technique where light waves are sent through a sample and the reflected light is then measured with a high precision spectrometer. The measured angles of polarization and intensity of the light that is reflected off the sample allows for determination of various optical parameters of the sample. FTM is a state of the art ellipsometer that supports many different measurement techniques such as spectral, variable angle spectral, variable angle scanning, and variable angle step scan measurements. It has a temperature range between -150°C and 350°C, making it suitable for investigating temperature-dependent effects. It includes a highly automated sample stage with a maximum area of 20 mm x 20 mm and 12-bit resolution, used to accurately measure the position and orientation of samples. RUDOLPH FTM also comes with an autofocus system, ensuring data precision and repeatability. FTM executes its measurements with highly precise angle and light intensity measurements, allowing for the determination of various optical parameters for surface and thin film analysis. It can measure optical constants such as refractive index, reflectance, absorbance, transmittance and extinction coefficient, as well as layer thickness, optical anisotropy and compositional changes. It has been designed to have am extremely low noise performance with up to a 0.05 degree accuracy for angle measurements and a 0.002 degree drift over 10 hours. RUDOLPH FTM is the perfect example of a powerful and highly precise instrument that can be used for various applications such as the measurement of semiconductor layers, pharmaceutical and biological surfaces, optical multilayers, and many more. It is also an excellent instrument for research and development in optics, and has been used in laboratories around the world. FTM is truly a powerful ellipsometer which delivers precise results every time.
