Import Tips
• Specify confocal resolution (<1μm) and Raman spectral range proving advanced chemical analysis microscopy
• Optical microscope primacy doesn't override; classify by chemical analysis function per Chapter 90 notes
• Stage automation documentation prevents 8479 robotic stage classification
