Factors such as remaining cleaning agent, dirt, and minor hairline fractures are canceled so that only deep defects such as scratches and chips are detected.
Images in which only the dents or chips are extracted are created without being affected by the complex printed background.
Glare, which affects inspections negatively, is eliminated to enable stable inspections.
These lights can be used as lights that have approximately three times the intensity of conventional lights. This enables imaging with very fast shutter speeds and macro lenses with optical magnification.
With conventional lights, the brightness is insufficient, which makes it impossible to perform inspections.
Sufficient brightness is provided by the CA-DRW5X.
Image the depth-of-field measurement target with a shutter speed of 1/240 and a macro lens with an optical magnification of x0.5.
With conventional lights, even if the aperture is reduced, the best depth-of-field that can be obtained is approximately 2.5 mm 0.10".
With the CA-DRW5X, the aperture can be reduced sufficiently, which makes it possible to obtain a depth-of-field up to approximately 7 mm 0.28".
