Laser Displacement Sensors
Laser displacement sensors focus a semiconductor laser beam on a target and use the reflectance of the beam off the target to determine the presence of a target and distance to it.
- Measuring distance.
- Detection of presence or absence of a feature.
- Confirmation of part or object passage.
- Positioning of work piece.
- Works in harsh environments.
- Some devices can achieve measurement precision down to .004 mils (0.1µm).
