Marks photos of the rig he uses to align the lenses and mirrors in the beam splitter. First photo if of the beam splitter. Second is a over view of the rig. Mark used a red laser to tell where he should be aligning the beam splitter too. And marked this location on a white piece of paper (IMG_2667-IMG_2668, IMG_2670-IMG_2671). When attaching the white light fiber optic Mark used as input for the white light this was aligned before starting the alignment of the beam splitter (IMG_2673 - IMG_2703). And then used white light to do the alignment. One issue Mark saw was when the beam splitter was aligned using the white light and you then used the red laser to check the alignment the red laser was always offset (IMG_2704-IMG_2705). Not sure why. Once the VIS light was aligned he then adjusted the NIR columators and mirror to get the NIR output aligned relative to the VIS alignment (IMG_2723 - IMG_2732 ).
