9.2.14. Protective front window, including O-Ring (E-PW)

As a spare part, the protective front window with the needed O-ring, is orderable. Especially in
harsh environments, the front window suffers and solid particles could influence the infrared
light transmissivity. The front window protects the sensor lens and is easy exchangeable.

9.2.15. Polarizing filter end cap for use in high temperature applic. (E-PFEC)

For Endurance® series devices, a specific Polarizing Filter End Cap is available for use in
high temperature applications. The small inserted Polarizing Filter will not fit in the standard
Endurance® End Cap. The filter shall protect your eyes, when sighting on bright, high
temperature targets through the visual sighting port. The filter does not affect measured
energy. It is solely for viewing comfort. Rotate the outer portion of the filter until you achieve
the desired visual attenuation.
