Abstract
The invention provides improved fiber optic probe assemblies which utilize a configuration of gradient index (GRIN) lenses to deliver light to a focal point and collect light for analysis from the same focal point. Also provided are methods for manufacturing the probe assemblies and related methods of spatially precise spectroscopy using the probe assemblies.
