The spectrometer systems that compose the Raman RMP-300 Series have an integrated fiber optic probe with a small X-Y-Z stage, compact laser, high-throughput spectrograph and CCD detector. No utilities such as coolants are required, allowing the system to be used almost anywhere. The flexibility of the optical fiber coupling enables remote measurements by locating the probe right at the sample. The fiber optic probe features an integrated CCD camera for sample positioning and capture of digital sample images. The series consists of six models, the 310, 315, 320, 325, 330 and 335, ranging from small, portable units suitable for in-situ measurements to research-grade systems.
