Cessna AWR P-17 Window Inspection Prism Kit

A specialised diagnostic tool kit used to inspect acrylic or glass aircraft window panes for hidden stress cracks and fractures around mounting bolt holes and edges. 

Included in this kit are:

• 1 X Inspection prism: An optical block with precise angles to look past obstructions.

• 1 X 1 oz Bottle of liquid couplant: Eliminates the air gap between the glass and prism, preventing light refraction errors. 

• 1 X High-Intensity light source: Illuminates the hidden edges and bolt holes, reflecting cracks back up to the prism viewer. 

Comes in a protective carrying case to prevent scratching to the prism.
