FemtoFiber bCARS
宽频带（bCARS），脉冲（iSRS）和标准拉曼光谱仪（CARS / SRS）的激光系统
- 使用bCARS的宽带覆盖范围<500-> 5500 cm-1
- 光谱分辨率<15 cm-1
- 可调CARS 选项，覆盖范围<1100-> 3700 cm-1
- 集成的延时和频率调制选项
- 简单，交钥匙且紧凑的解决方案
测量速度，最高光谱覆盖范围和易用性对于高级CARS / SRS显微镜至关重要。基于这些要求，TOPTICA开发了FemtoFiber bCARS系统，该系统是宽带CARS显微镜的理想激光解决方案，涵盖了<500-> 5500 cm-1的超宽带光谱范围。对于相干拉曼激发，该激光器具有980-1400 nm（<25 fs）的超宽带激光器输出，这使波长调谐变得过时，简化了激光器设计，并提高了测量速度。可调CARS / SRS的其他选项以及脉冲SRS（iSRS）的短脉冲选项使该激光系统成为您研究的最终选择。交钥匙且紧凑的全光纤设计使操作变得非常简单，使您可以专注于研究。
