InPhotonics: Imaging Fiber Optic Raman Probe

Imaging Raman Probe

The imaging probe is a video camera integrated with a standard fiber optic Raman probe in a handheld housing. The sharp 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 field of view of the imaging system is about 0.1 inch in diameter.
