PE LAMBDA 950

[ Variable Angle Specular Reflectance Accessory (VASRA)] The VASRA provides the ability to measure the specular reflectance of a sample surface at angles of incidence. It is easily installed in the sample compartment of the LAMBDA-900/850/950/1050. The VASRA is ideal for measuring the reflectance of materials at various angles and wavelengths, characterizing mirrors and determining the refractive index and thickness of thin films. The characterization of thin films for optical components is important in semiconductor, micro-machining, defense, materials and other high technology applications.
