Used GAERTNER L116 #75352 for sale

GAERTNER L116 is a state-of-the-art spectroscopic ellipsometer. It is designed to measure the properties of thin films, surface species, and multi-layer coatings. The system utilizes both precision optics and dual polarizing beamsplitter technology to measure the optical characteristics of a material sample. This includes parameters such as index of refraction, extinction coefficient, film thickness, surface roughness, and optical constants of materials. L116 is equipped with a variety of components enabling scientific research, product development, and quality control. The system is based on a HeNe laser that is used to measure the optical properties of samples. The laser is capable of generating multiple wavelengths, in either continuous or discrete mode, allowing for more accurate measurements. The laser is connected to a detector assembly consisting of a photodiode and charge-coupled device (CCD) camera, both of which are used to measure the intensity of light reflected by the sample in both directions. The detector assembly also includes two polarizers, which allow for the measurement of both the polarization of light reflected by the sample and the orientation of the polarization of the reflecting light. GAERTNER L116 includes a computer-based automation and control software, as well as a variety of accessories for both data acquisition and sample positioning. These include high precision translation stages and sample holders compatible with the system. The software also allows for programming of different measurement sequences, enabling automated testing of 4-, 6-, and 8-inch samples. L116 is considered to be the standard for reliable characterization of thin films and coatings. It provides researchers and engineers with the ability to precisely measure the optical properties of a sample down to nanometer resolutions. It also enables simultaneous analysis of various surfaces, allowing for a more comprehensive understanding of the materials' characteristics. The accuracy and repeatability of GAERTNER L116 enables confidence in the quality control of manufacturing processes, electrical characterizations, and validation of optical designs, making it a valuable tool for a variety of industries.
