MRID
Dual-Laser Micro-Raman with 360° Polarization
MRID puts two lasers inside one micro-Raman system and lets the software do the switching, so a sample can be measured at two excitation wavelengths without anyone touching the optics. Its distinguishing feature is automated polarization: the system scans the full 360° of linear polarization for each laser, which is what makes oriented and layered materials readable rather than merely visible.
