Used SENTECH SE 400 #9027536 for sale

SENTECH SE 400 ellipsometer is a highly accurate and reliable optical device for surface characterization. It is a complete ellipsometry and reflectometry system for determining the optical properties of thin films and coatings on opaque substrates. SENTECH SE400 can measure surface layer thicknesses of up to 1000 Angstroms, and can be used to measure both thin films and complete multilayer stacks. SE 400 utilizes a unique dual-beam front reflected polarization technique to analyze complex optical responses that are not possible with traditional single-beam techniques. This advanced technology allows for more reliable measurements, particularly when dealing with high refractive index films and challenging coating profiles. The user-friendly graphical interface of SE400 simplifies the data acquisition process and allows for quick analysis of the results. SENTECH SE 400 consists of an ellipsometer head, light source, sample holder, signal processor, and computer monitor. The light source utilizes a 150-watt lamp and a HeNe (helium-neon) laser with adjustable power output for exceptional sensitivity. The sample holder is motorized, flexible, and allows for easy changing of the angle of incidence. The signal processor is an advanced digital Fourier analysis system that provides quick and accurate evaluation of the signals. SENTECH SE400 is suitable for a wide range of applications, including thin film characterization and development, optical film monitoring, materials development, and process control. This instrument is also ideal for characterizing surface roughness, metallization layers, and a broad range of optical coatings. Additionally, SE 400 lends itself well to being used in automated production systems, allowing for quick and reliable quality control and optimization. In summary, SE400 ellipsometer is a powerful and reliable solution for accurately measuring and analyzing thin films and substrates. With its advanced dual-beam technology, flexible sample holder, and compatibility with automated production systems, SENTECH SE 400 provides a cost-effective and comprehensive solution for measuring optical properties.
