Micro-area transmissivity and reflectivity measurement system is used to measure the reflectivity of the spectrum in tiny area. The integrated halogen tungsten lamp can be used continuously for 2000 hours with a stability of > 99.99%. The reflectivity measurement system performs non-destructive, fast and high-precision measurements on samples. The spot size is 5um (actual measurement), and the transmissivity and reflectivity of small objects can be tested. With an automatic platform, mapping scanning can be performed.
