alphaCART – Mobile Raman System

alphaCART is Oxford Instruments' mobile, confocal Raman system for all applications that require bringing the lab to the sample.
 

alphaCART’s Raman probe can be flexibly positioned in front of bulky, immovable or precious objects that can’t be transported to a microscope or that don’t fit under one. 

The system's high confocality and signal sensitivity also allow measurements through protective glass and windows, which enables studies of gases or chemical processes inside reaction chambers and other enclosures. Researchers working in the arts and archaeology, geo- or materials science will especially benefit from this versatile and powerful analytical tool.

Key Features

• Freely positionable, fiber-coupled Raman probe
• High spectral and spatial resolution, confocality and signal sensitivity
• Sample survey with white-light illumination and color video camera
• Objective, laser and spectrometer configuration options
• Rolling flight case containing and protecting all components (optional)
• Advanced data post-processing
• Polarization-sensitive measurements (optional)
• Full compatibility with witec360's upgrades and accessories

Benefits

The positioning flexibility of the alphaCART probe combined with its high confocality and signal sensitivity enables the nondestructive analysis of:

• Oversized samples that don’t fit under a microscope
• Fragile or precious objects that can’t be moved to a lab
• Samples that exhibit fluorescence, as background is minimized
• Inclusions in various materials
• Processes inside reaction chambers
• Gases and liquids inside glass containers, as even weak signals can be detected
• Samples at high temperature, as background from black body radiation is effectively minimised
