Light field length
The required light field length of the light box results from the
camera measuring range plus a reserve of at least 50 mm on both
sides.
The light field length of the light box must always be
greater than the camera measuring range.
An overview of all available standard light boxes can be found in
chapter Light Boxes, page 186.
Distance light box – web of material
The smaller the distance from the light box to the web of material,
the greater the hazard that soiling on the light box will lead to
incorrect measurements. For standard applications, we therefore
recommend a minimum distance of 100 mm.
