2. Hot spots must be clearly detected, when in front of a cold background (50% energy response).
Remark : The measured area for 50% energy response is approximately ⅓ of the area size of the
measured spot for 90% energy response.
Refer to section 2.2
Optical Specifications , page 11, for basic versions of optical resolution values for
the various models.
Figure 7: Relationship between scan line width and distance to target
The relationship between the scan line width (L) and the distance (D) to the front side of the
linescanner housing is defined as described above. For long distances, the scan line width is about
twice the measurement distance (90° FOV).
5.2 Mounting
The linescanner can be installed with the mounting holes of the linescanner housing. This type of
setup is recommended for permanent installations where higher stability is desired.
Prevent all contact between heat sources and the linescanner to protect the linescanner from
overheating.
L = Scan line width
D = Distance to target (measured from front
surface of housing)
90° FOV:
D = L/2
