Table top spectrophotometer LTS-A13

Overview

Transmitted spectrophotometer LTS-A13 with table top design is used to measure the transmittance, absorbency, concentration as well as reflectance of the material. Equipped with SCS system for best measurement repeatability & accurate measurement of surface color of material. The double grating & double optical path splitting system & ETC (every test calibration technology) produces 0.01% resolution, color balance intensity across visible spectrum & highly accurate measurements.
