FAQS on confocal displacement sensor

Q: What is a confocal displacement sensor?

A: A confocal displacement sensor is a high-precision optical device that uses confocal microscopy principles to measure distance or displacement. It achieves micron or sub-micron resolution by focusing light onto a target and detecting reflected signals. This technology is ideal for non-contact measurements on reflective or transparent surfaces.

Q: How does a chromatic confocal sensor work?

A: A chromatic confocal sensor uses a multi-wavelength light source and a lens system to create wavelength-dependent focal points. The reflected light’s wavelength corresponds to the target’s distance, enabling precise displacement measurement. This method allows measurements on tilted or uneven surfaces without recalibration.

Q: What are the key applications of confocal sensors?

A: Confocal sensors are widely used in industrial automation, semiconductor inspection, and biomedical engineering. They excel in measuring thin films, transparent materials, and microstructures. Their non-contact nature also makes them suitable for delicate or high-speed applications.

Q: Why choose a confocal sensor over other displacement sensors?

A: Confocal sensors offer superior accuracy (±10 nm to ±1 µm) and work on diverse materials, including glossy, rough, or translucent surfaces. Unlike laser triangulation sensors, they avoid speckle noise and perform well in challenging environments like vacuum chambers or high-vibration settings.

Q: Can chromatic confocal sensors measure multiple surfaces simultaneously?

A: Yes, chromatic confocal sensors can measure layered or stacked surfaces (e.g., glass thickness) in a single scan. By analyzing different reflected wavelengths, they detect distance variations across multiple planes. This capability is critical for applications like OLED layer inspection or medical device testing.
