- Non-contact measurement
- Measuring with light instead of touching the part, so nothing wears out, nothing gets scratched and the line doesn't stop.
- Laser triangulation
- A laser spot or line shines on the part and a camera watches from an angle. Where the light appears tells the sensor the distance or shape.
- Profile
- A cross-section of the part's surface, like slicing it and looking at the edge. Scanners take thousands per second.
- Tolerance
- How far a dimension may be from the target and still be a good part, for example ±0.1 mm.
- Resolution vs accuracy
- Resolution is the smallest change a sensor can notice. Accuracy is how close its reading is to the true value. You need both.
- Wavelength (nm)
- The colour of the laser. Blue (405 nm) works better on shiny or hot surfaces; infrared is invisible to people.
- Fiber laser
- The modern industrial laser source used for marking, welding and cleaning: efficient, compact and long-lasting.
- MOPA
- A type of marking laser whose pulses can be tuned. It can make black marks on aluminium and coloured marks on steel.
- CW / pulsed
- Continuous wave means the laser is on constantly, good for welding. Pulsed means short bursts, gentler for cleaning delicate surfaces.
- Seam tracking
- A sensor that finds the joint between two parts and guides the welding robot along it in real time.
- Laser class (1–4)
- The safety rating. Class 1 is safe in normal use; Class 4 needs guarding, safety glasses and trained staff.
- IP rating
- How well a device is sealed against dust and water. A higher number means tougher conditions.
- PLC
- The industrial computer that controls a production line. Our sensors send their results to it.
- Commissioning
- Installing, setting up and proving the system works on your line, ending with an agreed acceptance test.
