ABSTRACT:
An adjustable fiber optic polarizer (10) comprising tubular member (14) and a bulk polarizer (12) disposed within tubular member (14) and including a two-axes adjusting device (20) disposed in each end of the tubular member (14). Interface device (40) can be positioned in the two-axes adjusting device (20). The two-axes adjusting device (20) supports an interface device (40) which connects the fiber optic to the graded index lens (42). Adjusting device (20) permits two-axes motion of the supported lens (42) with respect to the bulk polarizer (12). The two-axes positioning device (20) can also be rotated with respect to the bulk polarizing device (12) for a maximum optical throughput and polarization extinction ratio.
