Features of Panasonic measuring systems
Coordinate measurement technology
The profilometer’s coordinate system consists of three reference flat surfaces (mirrors) independent of the stages. The length of each of the X, Y, and Z axes is measured with a resolution of 0.3 nm with the laser interference method using a frequency-stabilized He-Ne laser as the light source. This method suppresses the influence of squareness and straightness of the stages to achieve a high-accuracy measurement.
- Measurement error due to the coordinate axes: 0.05 µm max. (up to 100 mm), 0.3 µm max. (up to 500 mm)
High-accuracy scanning and measurement of a measured object is feasible due to the use of ultra-low measuring forces.
The stylus is held by the micro-air slider, and the focus laser detects the movement of the stylus. The position of the AFP is tracked in line with the shape of the measured object to keep the measuring force constant.
- Measuring force: 0.15 to 0.30 mN (15 to 30 mgf)
* UA3P-3100/4000: 0.05 to 0.30 mN, UA3P-5000H: 0.10 to 0.30 mN
- Stylus: A diamond stylus with a tip angle of 30 degrees and a radius of 2 µm can be used.
Core software technologies
High-speed and high-accuracy measurement is possible with a simple operation. A variety of design information is supported. Installation errors in the measured object are corrected in three dimensions to enable accurate profile measurement.
