What is the general accuracy?
Our 2D non-contact optical vision measuring instrument measures a product’s two-dimensional planar dimensions, and it only outputs in-plane measurement data. That said, certain special products demand both 2D planar dimension testing and product height measurement. Under such circumstances, can a standard 2D measuring instrument satisfy these measurement needs?
A 2D optical vision measuring instrument is a non-contact optical device that measures a product’s flat 2D sizes, so it only provides in-plane data. However, some special products need both 2D size measurements and height checks. Can a standard 2D measuring instrument handle these tasks?
The answer is yes, the quadratic element can measure the height in the industry is not a new topic, can measure the height of this kind of quadratic element we generally called 2.5D or 2.5 dimensional element. The following, for you to introduce the quadratic element measuring instrument is how to measure height and the accuracy of the measurement results.
Image altimetry
We have integrated a dedicated height measuring module into our measuring instrument software. We first adjust one reference plane via the focal length, then identify a second plane. The measured height value is the difference between these two planes, and we can control the measurement accuracy to within 0.005 μm.
Measurement accuracy: 0.001mm
Height measurement by contact method
Install the probe on the Z axis; The contact method is used to measure the results directly. This method also needs to add a module to the secondary image measuring instrument software.
Measurement accuracy: 0.003mm
The above two methods are only suitable for simple measurement of the height of the product, if you need to measure the space size and some composite dimensions that is not good. The height measurement method and high accuracy of the quadratic element measuring instrument are briefly introduced here. If you have other questions, please consult Komanie.
