Window
Window is a transparent medium mounted front of the engine.
Window Placement
The window should be mounted close to the front of the engine (parallel, no tilt). The maximum distance is measured from the front of
the engine housing to the farthest surface of the window. Since unwanted reflections can occur at either surface, the window thickness
is suggested to be as thin as possible.
Recommended window placement is illustrated below:
Window Material Requirements
Window material must be clear and show high permeability to the illumination light wave of the engine (625± 20nm).
The maximum allowable thickness for the window is 1.5 mm.
Window Size
Window size should be designed to ensure the illumination and aiming envelopes shown. The engine`s envelope diagrams are
illustrated below.
