The ARTA is a fully automated spectral goniometer tool that uses an integrating sphere as detector to measure directional Reflectance and transmittance in the solar wavelength range. The ARTA transforms a spectrophotometer into a flexible and accurate tool for Variable Angle Spectrophotometry for thin film analysis.
