For Individuals Looking at 3D Shape Measurement Systems

When looking for the best way to perform profile (3D) measurement, there are a number of important factors to consider, including the type of measurement system and the installation environment. Selecting equipment that doesn't adequately meet your needs can lead to insufficient precision and increased man-hours during production. This site is designed to help users determine the best way to perform measurement with confidence in regards to a 3D shape measurement system.

How to Measure 3D Shapes

Find the best measurement method and the right equipment to measure "3D Shapes".

The measurement location is 10 × 10 mm or smaller

Example Application: Measuring the height of balls on BGA

Optimal measurement system

Optimal measurement systemReflective 3D Laser Displacement Sensor

The WI-5000 Series captures 80,000 points of height data instantaneously across a maximum measurement area of 10 × 10 mm.
The principles of white light interferometry result in highly accurate micron-level measurements with no influence from the material, color, or blind spots.

KEY POINTS

Even if the target is at an angle, automatic correction allows the surface shape to be captured accurately.
This makes highly accurate micron-level measurements possible.

The measurement location is larger than 10 × 10 mm (inline measurement)

Example Application: Profile measurement of connecting rods
