The optics attachment of visuReal portable is required due to the following reasons:
- multiple optical magnification = more accurate measurement results.
- The optics attachment determines the measuring distance of 1meter (between optics and customer).
- 4X optical zoom and higher resolution of the images, for exact calculation of the measurement area.
- The customer can fix a point, marked by the red ring, that is in the middle of the optics.
- The customer can thereby look in the middle of the measuring instrument. This avoids parallax errors .
