Used SOPRA EP-12 #9298855 for sale

SOPRA EP-12 Ellipsometer is a high-precision optical equipment designed to measure the thickness and optical properties of thin films. It is capable of measuring the thickness of the films from 1-300 nm with an accuracy of +/- 0.2 nm. Furthermore, the system can measure the optical constants (index of refraction and extinction coefficient) of the coating material. The unit is equipped with an ultrafast pulsed laser diode source, an interferometer, a detector and a motorized rotation stage. The high-power laser diode produces short pulses of infrared light that are directed on the surface of the thin film. The laser light is then redirected by the interferometer and combined coherently on the detector. The detector measures the phase shifts in the reflected light for different angles of incidence. By rotating the sample at angles between 30 and 150 degrees, the machine can then determine the optical characteristics of the film accurately and quickly. The software that is included with EP-12 is easy to use and provides detailed data analysis. The software can interpret various models such as Cauchy, DB, and B-Kolosov, which can be used to calculate the refractive index and extinction coefficient of the thin film. Additionally, the software provides advanced functions such as mapping, thickness, relative pathlength and bulk parameter measurements. SOPRA EP-12 Ellipsometer is a reliable tool for characterizing the properties of thin films. Its precision and accuracy make it an ideal tool for measuring the optical constants of a variety of thin film materials. Its robust design and powerful suite of software features make it an attractive choice for both research and production applications.
