Imaging Raman Probe

The image from our imaging probe
The laser spot size is 100 um

Our imaging probe can be either handheld with a focusing spacer or mounted on a microscope stand

The imaging probe is a video camera integrated with a standard fiber optic Raman probe in a handheld housing. The image from the video camera shows the excitation laser spot, which facilitates alignment of the sampling location. The camera is connected to a PC of your own choice via a USB port. A software driver for the camera is included.

The Raman signal is collected efficiently by the objective lens on the probe tip, which has a high numerical aperture and is broadband coated. The objective lens also serves as part of the imaging system. The filter for the laser sopt imaging can be customized according to the laser power in use. The field of view of the imaging system is about 2mm X 1.5mm.
