Table top spectrophotometer LTS-A13

Table top spectrophotometer LTS-A13


Transmitted spectrophotometer LTS-A13 with table top design, side ward caliber is used to measure the transmittance as well as reflectance. The use of D/0 diffused light, CLEDs, dual optical path spectrum analysis technology & ETC every test calibration technology gives 0.01% resolution, balance intensity across visible spectrum & highly accurate measurements.
