Coaxial Lights for Flat Reflective Parts
Use coaxial light on a flat reflective face. The beamsplitter sends light along the lens axis, so a flat face returns bright and a tilted scratch goes dark. Read the aperture and working distance on the coaxial model row. LXV-3COH is the high-power coaxial series.
What applications are coaxial lights for flat reflective parts best suited for?
Open the series, then send the part.
- Flat reflective metal or glass
- PCB fiducials and mark points
- Wafer and package surfaces
- Printed or engraved marks on planar parts
When should you avoid using coaxial lights for flat reflective parts?
Use another geometry when the surface does this.
- The part is curved or uneven
- The defect needs dark-field shadow
- The field of view exceeds the optical aperture
What are the primary selection inputs for coaxial lights for flat reflective parts?
Send these with the part.
- Optical aperture size
- Camera field of view
- Working distance
- Surface flatness
- Wavelength and polarizer needs

What are the most frequently asked questions about coaxial lights for flat reflective parts?
When is Coaxial Lights for Flat Reflective Parts useful?
Use coaxial light on a flat reflective face. The beamsplitter sends light along the lens axis, so a flat face returns bright and a tilted scratch goes dark. Read the aperture and working distance on the coaxial model row. LXV-3COH is the high-power coaxial series.
What information is needed to select a light?
Start with Optical aperture size, Camera field of view, Working distance. Share target images and the inspection requirement so the arrangement can be checked on the actual application.
