Hey guys, after a thorough search of going through sled parts looking for a PBS that could combine two 445 lasers without too much loss, I've found a good option. The PBS/Reflector combination that is mounted vertically, pointing up to the red read lens in the GGW-H20L and GBW-H10N is just about right for the job. Pass the horizontally polarized beam off the internal reflector and through the PBS, and pass the vertically polarized beam straight in off the PBS and they appear to be combined with acceptable losses.
Note the beam entering from the bottom looks skinnier because you're looking at it along the skinny axis.
