METHOD AND APPARATUS FOR CONDUCTING RAMAN SPECTROSCOPY

摘要

A Raman probe comprising a first optical fiber for receiving and transmitting laser excitation light from a light source; a first filter for receiving light from the first optical fiber, passing the laser excitation light and blocking spurious signals associated with the light; a second filter for receiving light from the first filter and directing the light toward the specimen; focusing apparatus for receiving the light from the second filter, focusing the light on a specimen to generate the Raman signal, and returning the Raman signal to the second filter; wherein the second filter filters out unwanted laser excitation light before directing the Raman signal to a second optical fiber when it receives the Raman signal from the focusing apparatus; and a second optical fiber for receiving and transmitting the Raman signal from the second filter to a light analyzer and a method of using the same.
