Perkin Elmer, 01860796, Fixed-Angle Specular Reflectance Accessory

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
