Fixed-Angle Specular Reflectance Acc

Fixed-Angle Specular Reflectance Accessory.The Fixed-Angle Specular Reflectance Accessory enables you to obtain a spectrum of any flat, reflecting surface on plate or sheet material. Includes Flat Reference Mirror and three Aperture masks (2 mm, 5 mm, and 10 mm). Good quality spectra can be obtained from films on glossy flat surfaces, shiny paper, metallic surfaces, and semiconductor wafers such as silicon and germanium using the PerkinElmer Fixed-Angle Specular Reflectance Accessory. You can also obtain high-quality spectra of surface-treated materials, coatings, thinly lubricated surfaces, resin, and molded plastic surfaces. In semiconductor technology, Fixed-Angle Specular Reflectance is the technique of choice used to map the thickness of epitaxial layers on semiconductor wafers. Benefits Include: Easy to mount in sample compartment Three interchangeable aperture masks provided for studying small sample areas Optimized optical design and easy installation
