InPhochelle High Resolution, Wide Range, High throughput, Compact Raman System

High resolution RS2000 system provides research-grade performance in a rugged spectrometer design.The "InPhochelle" is a compact Raman instrument offering high resolution (down to 2 cm-1) across the full spectral range (200-3500cm-1). The design uses fast f/2.8 optics for excellent throughput. Spectral acquisition is fast and highly reproducible. Since the only moving part is the shutter, the instrument is very rugged.

The 3-stage cooled CCD operates at -55°C, providing excellent sensitivity, spectral stability, and low background noise.

The "InPhochelle" is available in two standard configurations distinguished by the laser choice, 670 or 785 nm excitation. The system includes InPhotonics' data acquisition package and GRAMS AI manipulation software operating on a PC, laptop, or netbook. The simplest configuration utilizes an InPhotonics Raman Probe for normal chemical characterization. More complex applications are supported by a variety of optical fiber Raman probes for process control and high-temperature applications.
