3.9.8 ESA – Extension Sleeve Adapter Description and Dimensions
This is a special accessory for Sensors with the Dirty Window Detector (DWD) option. The ESA serves
as protection sleeve over the DWD optics and as the mechanical interface between the Sensor and
other Modline 5 accessories. The ESA is used in the following combinations to provide air purging or
create a dead air space zone in front of the Sensor optics to help keep them clean. The combinations
also provide shielding from stray radiation emanating from high temperature targets. The APA air
purge, shown in combinations one and two, provides the best performance. The use of an APA is
required for large targets over 1000 °C.
