光谱系统
HARPIA 综合光谱系统在紧凑的空间内可以完成多种复杂的时间分辨光谱的测量。它提供直观的用户体验和方便的日常维护，满足当今科学应用的需求。
HARPIA-TA 是一个瞬态吸收光谱系统。可根据特定测量需求选配定制选项和扩展模块来定制 HARPIA 系统。尤其是它可以使用时间相关单光子计数和荧光上转换 (HARPIA-TF) 、第三光束传输 (HARPIA-TB) 和显微镜 (HARPIA-MM) 模块进行扩展。HARPIA 的设计使其在测量模式之间轻松切换，并配有专用数据采集和分析软件。每个模块都包含在一个整体腔体内，确保其出色的光学稳定性和最小的光程长度。
HARPIA-TG 是一种新型瞬态光栅光谱系统，专门用于测量扩散系数和载流子寿命。全自动计算机控制的系统可以在几分钟内完成测量。
