Lumina Instruments is a Global Supplier of Innovative Optical Inspection Systems

for full-surface defect detection, mapping and classification on transparent, translucent and opaque substrates.

Founded by a team of experts with decades of experience in optical inspection, Lumina Instruments builds cutting-edge systems. These are for surface and internal defect detection. By utilizing 4 detection channels operating simultaneously, Lumina’s patented technology offers unmatched performance, enhancing yield control and management in key industries including semiconductor, consumer electronics, as well as the rapidly growing glass market in high-tech products.

Lumina Instruments is a privately held company headquartered in San Jose, California.


Lumina is working with four detection channels. They operate simultaneously to generate four separate images. Each channel aids in detecting and classifying certain defects:

Lumina Instruments, Innovative Optical Inspection Systems, Polarization, Reflectivity, Surface Slope, Dark Field

  • Polarization: Film Defects, Stains
  • Reflectivity: Scratches, Internal Stress*, Striations within Glass*
  • Slope: Scratches, Pits, Bumps, Surface Topography
  • Dark Field: Nanoparticles, Inclusions

*Reflectivity off of the top and bottom surfaces provides these results.
