Abstract
A chromatic confocal system for line-scanning an object. The system comprises a light module for providing a line-scanning light beam and a chromatic confocal lens module defining a first light pathway for directing the line-scanning light beam along said first light pathway and focusing the line-scanning light beam to impinge on a surface of the object. The lens module also defines a second light pathway for directing line-scanned light reflected from the surface of the object to one or more imaging modules. The line-scanning light beam has a predefined, limited range of wavelengths within the visible light spectrum.

A chromatic confocal system for line-scanning an object, the system comprising:
- a light module for providing a line-scanning light beam;
- a chromatic confocal lens module defining a first light pathway for directing the line-scanning light beam along said first light pathway and focusing the line-scanning light beam to impinge on a surface of the object, the lens module defining a second light pathway for directing line-scanned light reflected from the surface of the object to one or more imaging modules;
- wherein the line-scanning light beam has a predefined, limited range of wavelengths within the visible light spectrum.
A chromatic confocal lens module for a line-scanning system, comprising:
- an input for receiving a line-scanning light beam from a light source;
- a first light pathway for directing the line-scanning light beam along said first light pathway and focusing the line-scanning light beam to impinge on a surface of an object;
- a second light pathway for directing line-scanned light reflected from the surface of the object to an output;
- wherein the line-scanning light beam has a predefined, limited range of wavelengths comprising blue and green light wavelengths within the visible light spectrum.
