10.3.4 Right Angle Mirror
The Right Angle Mirror is used to turn the field of view by 90° against the sensor axis. It is
recommended when space limitations or excessive radiation do not allow for direct alignment of the
sensor to the target. The mirror must be installed after the bracket and after the Air Purge Collar and
screwed in fully. In dusty or contaminated environments, air purging is required to keep the mirror
surface clean.
When using the Right Angle Mirror, adjust the emissivity or transmissivity settings
downward by 5%. For example, for an object with an emissivity of 0.65, you adjust the
value down to 0.62. Or, you can keep the emissivity 0.65 and adjust the transmissivity from
1.0 to 0.95. This correction accounts for energy losses in the mirror.
10.3.5 Protective Window
Protective windows can be used to protect the sensing head from dust and other contamination. The
protective window can be directly screwed onto the sensing head.
The following table provides an overview of the available windows.
For correct temperature readings, the transmission of the protective window must be set
via the control panel in the communication box. See section 8.2
