Raman spectra of plastics - research data

This dataset contains Raman spectra of ten commonly used plastic types, acquired using a handheld Raman spectrometer with a 785 nm excitation laser. Measurements were performed across a spectral range of 3400–200 cm⁻¹, with varying laser powers (10–100%) to account for spectral variability. Each plastic type is represented by multiple spectra collected from samples differing in color, opacity, and thickness. The dataset was developed to support machine learning applications in plastic classification and identification. All files are provided in .txt format.本数据集包含十种常用塑料的拉曼光谱（Raman spectra），采用激发波长为785 nm的手持式拉曼光谱仪采集获得。采集光谱的范围为3400–200 cm⁻¹，通过设置10%–100%的可变激光功率以覆盖光谱的变异性。每种塑料均对应多组光谱数据，这些光谱采自颜色、透明度与厚度各不相同的样品。本数据集旨在为塑料分类与识别相关的机器学习应用提供支撑。所有数据文件均以.txt格式提供。
