Machine Vision Coaxial Lights
Use coaxial lighting for flat reflective targets where the camera needs light returning along the optical axis. It is useful for mirror-like planar parts, printed marks, fiducials, and surface features that appear with on-axis contrast.
Best fit
- Flat reflective metal or glass
- PCB fiducials and mark points
- Wafer and package surfaces
- Printed or engraved marks on planar parts
Likely to fail when
- The part is curved or uneven
- The defect needs dark-field shadow
- The field of view exceeds the optical aperture
Selection inputs
- Optical aperture size
- Camera field of view
- Working distance
- Surface flatness
- Wavelength and polarizer needs
