Stability: The dynamic feedback dual beam system and circuit ensure the stability of the baseline and ensure the stability of the instrument for a long time
Low stray light: The excellent optical system ensures that the stray light of the instrument is ≤ 0.015%T, which makes the test data of high concentration samples more accurate
Automatic 8-level spectral bandwidth (0.1, 0.2, 0.5, 1.0, 2.0, 3.0, 4.0, 5.0nm) is continuously adjustable to meet the needs of various sample testing, and the number of spectral bandwidths can also be customized
Light source replacement is simple and convenient: imported socket-type flange-type deuterium lamps and tungsten lamps are used, no need for optical path debugging when changing lamps, and maintenance is easier
Full PC operation: equipped with UV-Solution3.0 workstation software, easy to operate and rich in testing functions
Measurement of three-dimensional map: Make and analyze the three-dimensional map of the sample scanning map with "dynamic changes"
