The device comprises a housing for a first incidental beam issued from a first source of light, a second incidental beam issued from a second source of light, an optical measuring system, a photosensitive sensor respectively delivering beams reflected from the substrate and an electronic unit connected to a communication port. The optical measuring system is telecentric, the first incidental beam crosses a telecentric lighting system and the second incidental beam crosses an oblique lighting system.
