90 DEGREE AMICI PRISM ASSY FOR NIGHT VISION
Made for one of the military night vision scopes, this
90 degree assembly has a beautiful 45mm long amici
roof prism, a 2" optical window, and a negative lens
assembly. If you have the scope these were made for
(we don't know which one), you need this. If not get if
for the components, especially the amici prism which
inverts the image and bends the line of sight thru a 90
degree angle. Amici prisms are are excellent as prism diagonals in optical
systems because they erect the inverted image and can be used with your
telescope as a diagonal that keeps correct left/right orientation.
