Description

This study investigates the reflectance properties of various material treatments measured using a Hunter Lab spectrophotometer across a wavelength range of 350 to 1050 nm. A white standard was used as a reference, consistently demonstrating high reflectance (90-100%) throughout the spectrum. In contrast, four treated samples exhibited significant light absorption in the visible range, particularly between 500 and 750 nm, where reflectance decreased to 3040%. Reflectance increased markedly beyond 750 nm, reaching 80-90% in the near-infrared region. These results highlight the impact of the treatments on the optical properties of the materials, suggesting their potential application in areas requiring selective light absorption and reflection, such as optical coatings and quality management
