Raman and Photoluminescence (PL) spectroscopy are widely used in many fields including physics chemistry materials science biology semiconductor solar cell and medicine Until now there are mature commercial products It has many advantages such as non-contact measurements widely usages rapid mapping measurements and precise analysis To improve the scanning efficiency of these instruments we modify the optical design based on the design of traditional spectroscopy Here a hole mirror was also been imported in this system And two kinds of measurement method X-Y measurement and R-θ measurement method are being analyzed in this design of system However to verify performance of this spectroscopy we prepared many kinds of sample for testing such as CVD graphene mechanical exfoliation graphene supported and suspended graphene hydrogen-terminated graphene MoS2 and AlGaAs For experimental requirement polarized Raman spectroscopy has been used and Origin is our fitting tool for Raman or PL spectra by Lorentzian function Rapid mapping stage plays an important role in this research too It helps to execute the X-Y measurement or R-θ measurement method In final goal to these spectroscopy cheaper more convenience faster modularization design and automatic control by computer are been expected
