• 

  A AN/PVS-7 collimator assembly, comprised of multiple lenses and a triangular prism to duplicate the output image from one MX-10130 tube into both oculars

• 

  When disassembling, lenses and metal rings come out in the indicated order (left first, right last)

• 

  Step 1: Insert the lens with the convex side facing towards the collimator housing

• 

  Step 2: Insert one of the thick metal rings

• 

  Step 3: Insert the thick lens, convex side facing towards the collimator housing

• 

  Step 4.1: Three components needed to be placed together in a bundle

• 

  Step 4.2: Place the metal ring onto a flat surface for convenience

• 

  Step 4.3: Place the lens onto the metal ring with the convex side facing towards it

• 

  Step 4.4: Place the thin metal ring onto the lens

• 

  Step 4.5: The final result should look like this with each component stacked according to their collerated numbers from 4.1

• 

  Step 5: Insert the fully stacked components from step 4 with the thin metal ring facing towards the collimator housing

• 

  Step 6: Insert the final lens into the collimator housing with the convex side facing outward

• 

  Step 7: Screw in the lock ring to securely all the components in place
