• intros：{"brand_intro":"北光光电（Beijing Optical）成立于2010年，是中国本土新兴的光学机械制造商，总部位于北京昌平。公司专注于光谱仪器配套耗材的研发与生产，以\"极致性价比\"为核心理念。创始团队来自北京理工大学光电学院，拥有多项狭缝刀片加工专利。北光光电采用全自动数控磨床加工刀片，品控通过SGS认证。虽然品牌知名度不及卓立汉光，但凭借极低的价格和快速响应服务，在中小型实验室和职业院校中积累了大量忠实用户。","product_intro":"BG-SL系列狭缝组件是北光光电的入门级产品，采用45号钢刀片和普通微分头，狭缝宽度0-2mm，分辨率0.1mm。核心卖点：价格极低（仅为卓立汉光的60%）、现货直发、兼容主流单色仪。适用于教学演示、基础光谱实验及预算极度有限的场景。相比卓立汉光，其精度和耐用性明显不足，但价格优势巨大。用户评价为\"便宜够用，坏了不心疼\"。","key_specs":{"狭缝宽度范围":"0-2mm","分辨率":"0.1mm","刀片材料":"45号钢（发黑处理）","适用波长范围":"400nm-1100nm","安装接口":"定制法兰（需备注型号）","重复定位精度":"≤5μm"}}
