Sample Image ▶ Rice cracker
Lighting wavelength change × focus shift compensation
1450nm Visualization of water splashes invisible at other wavelengths
Visible Light Clear visualization of burn marks on brown rice crackers
850nm Burn marks on the rice crackers are no longer visible, and foreign objects (hair) are clearly visible
