Abstract
Disclosed herein are Raman probes that include: (a) a first optical fiber for receiving laser excitation light from a light source and transmitting the same; (b) a first filter for receiving light from the first optical fiber and adapted to pass the laser excitation light and to block spurious signals associated with the light; (c) a second filter for receiving light from the first filter and adapted to direct the light toward a specimen; and (d) focusing apparatus for receiving the light from the second filter, focusing the light on the specimen so as to generate the Raman signal, and returning the Raman signal to the second filter. The second filter is further configured so that when the second filter receives the Raman signal from the focusing apparatus, the second filter filters out unwanted laser excitation light before directing the Raman signal to a second optical fiber.
