| Application | Lighting device |
Before
Inspection with a conventional 2D camera or 3D inspection with a laser, etc.
After
Imaging with the newly developed specialized optical system.
This is a new lighting system suited to inspections of extremely shallow dents which are difficult to detect in 3D inspections with lasers etc. on mirrored surfaces (lustrous mirrors, glass, film, etc. ).
[Main characteristics]
(1) Possible to detect very slight roughness on the work surface with an ordinary area camera
(2) Imaging can be conducted in one shot, so scans do not take much time, as they do with 3D inspection
(3) Also compatible with production line cameras
(4) Can be colored depending on the angle
[Ex. ]
0 - 1. 5°: black
1. 5 - 2. 5°: blue
2. 5 - 3. 5°: green
3. 5 - 10°: red
10°+: black
*Monochromatic inspections are also possible.
(5) Suited to the inspection of extremely shallow dents in lustrous mirrors, glass, film, or the mirrored surface of metals etc. with high reflectivity which are difficult to inspect in 3D inspections using lasers.
*This system is not well suited to subjects that are not lustrous.
(6) Optimal for comparing OK work to not OK work on the work surface
*Height information cannot be obtained.
