Comparison to Typical RAMAN

---

Optical collection configuration allows coupling of Raman scattered light from an unfocussed Nd:YAG excitation source to be efficiently coupled into an optical fiber. 

High power excitation pulses are used while simultaneously avoiding sample degradation, multiphoton effects, and alleviating the need for deep sample penetration depths. 

No need for accurate focal plane adjustments. Light is collected from a large cross-sectional area, not a discreet focal point.
