Used RUDOLPH FE III #9283673 for sale

RUDOLPH FE III is a state-of-the-art ellipsometer used to measure the optical properties of a given sample. This precision instrument is capable of measuring the dielectric function of a material by shining polarized light on the sample and measuring the polarization state of the reflected light. The instrument uses two semicircle analyzers and a light source to measure the angles of refraction and reflection from the sample. The optical properties of a material can be determined by measuring the angle of the polarized light that is reflected from its surface. Depending on the direction of the light, the sample will reflect either parallel or perpendicular to the incident light depending on its susceptibilities. The reflected light is then measured to determine the optical properties of the sample. By measuring the ratio of the reflected light that is parallel to the incident light, RUDOLPH FEIII can determine the sample's complex index of refraction. It uses an integrating sphere to measure the intensity of the reflected light from the sample in order to calculate this complex index. In addition to its unique design, FE-III also has two other features that make it a University or industrial laboratory instrument of choice: its small footprint and its relatively low cost. The footprint of the instrument is approximately 200 mm x 260 mm x 130 mm, making it an ideal choice for areas with limited bench space. The cost of the instrument is also relatively low, whilst the accuracy of the measurements produced is extremely high. In conclusion, FEIII ellipsometer is a precision, state-of-the-art instrument that is capable of producing high-accuracy measurements of the optical properties of a given sample, even with a small footprint and relatively low cost.
