Multiple Inspection Solution Using Monochrome Line Scan Camera
By using a monochrome line scan camera, it is possible to simultaneously inspect multiple different defects such as stains and scratches on a single stage.
Features
- Multiple images of RGB line dome and coaxial lights can be acquired in one stage.
- Color images can be generated using a monochrome line scan camera.
- Capable of acquiring images with different exposure times.
- We can suggest customized coaxial units for high resolution.
Advantages of acquiring color images with a monochrome camera
- Compared with color cameras (Bayer, 3CCD, and Trilinear),
- There are more camera options available, allowing selection according to the inspection requirements.
- False color artifacts * are less likely to occur.
- Individual color adjustments can be made to suit what you want to observe.
* A color that does not actually exist, which may occur during pixel interpolation in images taken with a color camera.
Imaging Example: Appearance Inspection of Circuit Boards
A color image generated by superimposing images captured under R (red), G (green), and B (blue) illumination, and an image captured under coaxial illumination were obtained.
Metal housing component
Generated Image
Obtain an image that shows color information such as dirt on the resist and silk printing.
(Exposure time 30μs)
Obtain images that show irregularities on the PCB surface and patterns of circuit on the PCB.
(Exposure time 10μs)
Obtain a clear image of the engraved text on the mounted metal element.
Imaging Method
Images are captured by switching between R (red), G (green), B (blue) illumination and white light illumination.
Example System Configuration
RGB line dome light is a custom-made product. For more details, please contact your sales representative.
Cameras and lights can be selected according to your inspection requirements.
The system can also be used in configurations other than those described above.
