WolfVision EYE-12 User Manual - Handbuch (Seite 19)

Please consider light positioning for the EYE-12
carefully. Mounting the light too close to the unit will
cause reflections, mounting it too far away will cause
shadows.
The illustration on the right shows the recommended
position of lighting for the EYE-12. The distance from the
center of the unit to the center of the light should be
identical to the MAXIMUM image size (e.g. vertical
image size).
Example: If the camera is mounted 1400mm above the
working surface then the maximum vertical image size is
893mm (see "length" value in table on page 17 or use the
calculation program at:
www.wolfvision.com/wolf/indexdistance.html)
This means that 893mm is also the recommended
distance from the center of the unit to the center of the
light.
We recommend mounting the light like the position
shown on the right, because here shadows are not too
disturbing when pointing at certain details on a
document.
Due to the automatic white balance of the unit, it is
possible to use any type of light. WolfVision
recommends a diffused light with more than 300 Lux and
a homogeneity of less than 15% on the working surface.
To minimize reflections, please use the optional inclined
working surface (see page 19).
A very easy method to find the ideal light position for the
EYE-12 is the dedicated flash animation program on
WolfVision's homepage:
