Scattering of rays Rays having long wavelength Atoms & molecules UV rays having short wavelength are likely to hit atoms and molecules and tend to scatter.

Scattering of rays Near IR rays UV rays (Long wavelength) (Short wavelength) Scattering UV rays are short in wavelength and tend to scatter. Ideal to see surface of objects Easy to see details of surface, objects and scratches

Application examples of UV camera and lens + Surface inspection of circuits and soldering condition: Clearer to detect damage, dust or stain + Manufacturing and quality control of semiconductors: Leaves no damage nor effect on the objects + Usages with microscope in medical applications + Detection of forgery, falsified documents, bills and credit cards: *Genuine U. S. dollar bill does not emit light *Transparent stamp appears on latest credit card + Inspection of fiber optics + Inspection of oil contamination and leakage
