ultraviolet illumination การใช้

• Photography of the fluorescence produced by ultraviolet illumination uses visible wavelengths of light.
• Normally the polymer glows under ultraviolet illumination, but the fluorescence diminishes where a particle of the explosive adheres.
• The sample is then treated with a special dye which, under a microscope's ultraviolet illumination, makes surface layers glow distinctively according to their content.
• Under ultraviolet illumination, curium ( III ) ions exhibit strong and stable yellow-orange fluorescence with a maximum in the range about 590 640 nm depending on their environment.
• Most of this text was recovered in early 2009 by applying principal component analysis to the three color bands ( red, green, and blue ) of fluorescent light generated by ultraviolet illumination.
