Replacing the Lens
Before starting acquisition of images, the lens may need to be replaced according to the size and distance to the
object.
Relationship between Measurement Distance and Object
With the VIVID 910, three types of lens are available: wide-angle lens, middle-angle lens and telescopic lens.
A lens suitable for the size of the object and distance must be used.
M
emo
The closer the object to the VIVID 910, 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 910.
Select the most suitable lens by referring to the table given below.
