2D Optical micrometers. Measurement the geometric parameters of battery cells for electric car batteries.

2D Optical micrometers are designed for non-contact inline two-dimensional batch measurements of linear dimensions, diameters, angles, thread parameters, part shapes, run-out, etc. Optical micrometers use a “shadow” measurement principle whereby collimated laser light is transmitted towards a receiver. The edges of the shadow cast by an object in the beam’s path are accurately measured by the detector array inside the receiver unit.
