Replacing the Lens and Field Calibration

With the VIVID 9i, three types of lens are available: WIDE lens, MIDDLE lens and TELE lens. Be sure to mount the lens that best matches the subject’s size and distance. Before taking scans of a subject, most suitable lens for the size of the object and distance must be used.

Note

After changing the lens, you need to recalibrate using the field calibration system. For Field Calibration, refer to page 32.

Relationship between Measurement Distance and Object

Select the most suitable lens by referring to the table given below.

Memo

The closer the object to the VIVID 9i, the higher the measurement accuracy is. On the other hand, influences of shades produced due to roughness on the surface of the object can be reduced if the object is positioned far from the VIVID 9i.
