High-resolution imaging
Enough pixels on the defect to make a judgement possible.
What the algorithm cannot see is, in the end, what the optics failed to produce. DSTEK designs the optical train around the part and the defect. High-reflectance, transparent, curved and anodised surfaces — the ones other vision vendors decline — are where we start.

Optical Imaging System
Imaging modes
Five ways to make a defect visible, combined according to the part.
High-speed imaging
Full inspection without slowing the line.
3D imaging
Height, step and shape defects judged in three dimensions.
Ultra-sensitive imaging
Signal recovered under low light and low contrast.
Spectral imaging
Wavelengths beyond visible light separate materials and contaminants.
Optical Imaging System
Difficult surfaces
Conditions a standard optical module struggles to capture. Each is a part we have actually inspected, with the defects we caught.
- High-gloss paint Automotive paint — contamination, runs, dents, orange peel
- Mirror-finish metal Bearing raceways — pitting, scratches, indentation
- Transparent cover glass Phone covers — scratches, foreign matter, dents
- 2.5D curved glass Curved edges — micro-cracks, polishing marks
- Anodised aluminium Laptop housings — colour variation, black spots, contamination
- Black rubber Tyres and weatherstrip — bubbles, cracks, foreign matter
- Translucent film Battery blue film — bubbles, creases, lifting
- Die-cast machined faces Transmission housings — porosity, shrinkage, burrs
- Silicon wafers Wafer edges — delamination, chipping, micro-cracks
- Large panels (3.3m) Body stampings — cracks, necking, wrinkles
