Handheld probe for raman spectroscopy detection device

Abstract

A handheld probe for Raman spectroscopy detection is disclosed, designed for insertion into the human oral cavity for detection. The handheld probe includes a body, a first light-reflecting element, a second light-reflecting element, and a light-focusing element. The body has a head, a tail, and an internal channel connecting the head and tail, and the internal channel has a bent section. The first light-reflecting element is disposed within the internal channel and located in the bent section. The second light-reflecting element and the light-focusing element are respectively disposed within the internal channel and located at the head. The control and detection module of the Raman spectroscopy detection device provides a light beam that enters the internal channel via the tail, sequentially passes through the first light-reflecting element, the second light-reflecting element, and the light-focusing element, exits the internal channel at the head, and is projected onto an object.
