LICO Series
Illumination with no ghosting, using a specially coated half mirror.
Inspection Applications &
Example Images
Using a half-mirror structure, light is projected in the same direction as the camera’s optical axis, enabling uniform illumination of the entire target surface without casting shadows.
On-axis incident light is directly reflected from flat surfaces back to the camera, allowing stable contrast detection of patterns, printed marks, and fine defects.
Illumination influence caused by surface unevenness or height differences is minimized, enabling clear and undistorted visualization of printed characters, engravings, and circuit patterns.
Minimal variation due to illumination angle ensures high repeatability and reliability in alignment inspection and precision component inspection processes.
Features
- Mirror-Surface Alignment Inspection
- By utilizing the on-axis illumination characteristics of coaxial lighting, reference marks and datum features on mirror-finished surfaces can be detected without distortion, enabling precise measurement of alignment errors.
- Metal Surface Inspection
- Uniform front illumination is applied to metal surfaces, allowing hairline scratches, fine defects, and contamination to be stably detected with clear contrast.
- LCD and Display Inspection
- Uniform illumination of glass substrates and display patterns enables clear inspection of non-uniformity, pattern defects, and contamination without shadow interference.
- Surface Inspection
- Fine contamination, scratches, and defects on flat surfaces can be consistently detected with uniform image quality, independent of variations in illumination angle.
