What Are Chromatic Confocal Sensors?
Chromatic confocal sensors utilize advanced optical principles based on chromatic aberration and confocal technology to measure distances, thickness, and surface topography with micrometer precision. They work by focusing white light through a lens, which spreads into its constituent wavelengths (colors); each wavelength focuses at a different distance. When a surface is detected, only a specific color is reflected back and analyzed, providing highly precise spatial information non-invasively.
Key characteristics:
-
Non-contact measurement: No physical contact reduces risk of surface damage.
-
High precision: Capable of measuring tiny features on reflective, transparent, or rough surfaces.
-
Real-time feedback: Ideal for integration with automated inspection systems.
