4. Frequently Asked Questions About White Light Cameras
Q1: How does a White Light Camera differ from a laser scanner?
A1: White Light Cameras use broad-spectrum light to measure surface topology, capturing color and texture as well as geometry. Laser scanners rely on a single wavelength, which may limit color detection but often achieves longer range. White Light Cameras excel in fine-detail, short-range measurement with minimal surface preparation.
Q2: How to choose the right White Light Camera for industrial inspection?
A2: Selection depends on required measurement accuracy, scan range, resolution, and speed. Consider lens options, frame rate, and software compatibility for integration with existing workflows. Accuracy should match the tolerance requirements of the components being inspected, while the resolution ensures surface defects are detectable.
Q3: How is the calibration process performed for a White Light Camera?
A3: Calibration involves using a reference artifact with known dimensions. The camera captures the reference, and software adjusts measurement parameters to eliminate systematic errors. Regular calibration ensures consistent accuracy over time, especially when environmental conditions vary.
