Reinstall the Wedge Mount and Corrective Optics

In order to guarantee proper optical alignment of the

turret assembly, and in order to minimize the

mechanical strain in the corrective-optics assembly for

polarizing work, reinstall the wedge mount and

corrective-optics assembly per the following procedure.

Place the wedge mount in position on the stationary

base of the turret assembly, aligning the four screw

holes in the wedge mount with the tapped holes in the

stationary base (see

through the center bore of the wedge mount and screw

the corrective-optics assembly into the tapped center

bore of the stationary base (see

corrective-optics assembly until it is hand tight, then

back it off approximately ¼ turn. The barrel of the

corrective-optics assembly fits the hole in the wedge

mount with very tight tolerances, and this precision fit

holds the wedge mount in the proper physical location

so that the mounting screws can be reinstalled.

Use a suitable JIS screwdriver to reinstall four M2.6X25

pan-head screws to secure the wedge mount onto the

stationary base of the turret assembly (see

Figure 49 – Reinstall screws to secure the wedge mount

Use non-marring pliers or a suitable strap wrench to

grip the barrel of the corrective-optics assembly and

tighten the corrective-optics assembly a bit beyond

hand tight (see
