Portable Spectrophotometer LBN-PS131 employs concave grating spectrometry, a 45° ring illumination and 0° reception geometric optical structure to correctly measure sample reflectance and various colorimetric data. A large measuring aperture of 20 mm is provided for traffic signs, colour matching, and accurate colour transfer. The equipment provides good precision and stability for uneven samples with stripes or granular samples.
