UV rays having short 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
