Portable Spectrophotometer LBN-PS135 is a standard spectrophotometer with 45/0 geometrical optics structure (45 ring-shaped illumination, vertical viewing), adopting concave grating light splitting method. The unit accurately measures the reflectivity and various chromaticity data of samples. A user can customize the measurement aperture (Φ 8 / Φ 4 / Φ 2 mm) according to the sample measuring demands so as to meet the accurate colour measurement and quality control requirements.
