Table top spectrophotometer LTS-A12 has multiple measuring calibers with largest caliber of 25.4 mm, satisfies the measurement needs of samples of different size. It is possible to measure the color data of opaque samples and transmission and opacity of transparent or semi-transparent samples. Equipped with dual light path spectral analysis technology ensures precision and long-term stability of the instrument. The 8°/diffused illumination geometric design of lightning, provides full insight of the color data.catalog/Tabletop-spectrophotometer.pdf
