Figure Lengend Snippet: A. A schematic of the module. S1 – light source with collimator (840 nm), λ/2 – half-wave plate, M, M1, M3, M4, M6, M8, M9, M0 – plane mirrors, BS1, BS2 – beamsplitters (10:90, R:T), SM2, SM5, SM7 – mirrors (R = 700 mm), L1, L2 –achromatic lenses (fl = 175 mm), D – spatial beamsplitter, fb1, fb2 – fiber bundles with their schematic arrange of the offset aperture locations, PP1, PP2, PP – pupil conjugate planes, RP – retinal conjugate plane. With purple color rays for the non-steerable optical channel 1 (OCH1), green color for steerable optical channel 2 (OCH2), and blue shows common path. A top view. B. A side view of the last part of the module’s schematic.

Article Snippet: Between the dichroic mirror and the WFS, we located a pellicle beamsplitter (p, 10:90, reflectance:trasmission, BSN11, Thorlabs) to introduce the beacon (10 mW, SLD-mCS, Superlum, Ireland).

Figure Lengend Snippet: A schematic of the Indiana AOSLO with module. Components of the original system are indicated with small letters (sm1) and red rays, whereas components that were changed or added are indicated in caps (M1) and blue rays. S1, S2 – light source with collimator (840 nm, 780 nm, respectively), λ/2 – half-wave plate, M, M1, M3, M4, M6, M8, M9, M0, m0, m, m4, m9, m13, m17 – plane mirrors, BS1, BS2 – beamsplitters (10:90, R:T), d – dichroic beamsplitter, p – pellicle beamsplitter, SM2, SM5, SM7 – mirrors (R = 700 mm), sm1, sm12 – mirrors (R = 1000 mm), sm2 – mirror (R = 750 mm), dm3, dm11 – deformable mirrors, sm5, sm8 – mirrors (R = 500 mm), sm6, sm14 – mirrors (R = 400 mm), m7 – fast scanner, sm10 – mirror (R = 2000mm), m15 – horizontal scanner, m18 – vertical scanner, fm16, fm19 – field mirrors (R = 304.8 mm), L1, L2 –achromatic lenses (fl = 175 mm), D – spatial beamsplitter, WFS – wavefront sensor, PP – pupil conjugate plane, RP – retinal conjugate plane.

Figure Lengend Snippet: A schematic of the relation of the module to the original BMC APAEROS system. Beamsplitters (BS) already present in the APAEROS are used to optically couple the new module. S1, S2 – light sources with collimator (780 nm and 840 nm, respectively), BS1, BS2 – beamsplitters (10:90, R:T), L, L1, L2 – lenses, WFS – wavefront sensor, M, M1, M3-M6 – plane mirrors, SM2, SM5, SM7 – concave mirrors, D – spatial beamsplitter, fb1, fb2 – fiber bundles, PP1, PP2 – pupil conjugate planes, RP – retinal conjugate plane, red square represent the optics of the APAEROS system.

Figure Lengend Snippet: The confocal image was maintained over all displacements which did not redirect the steerable beam in a way that caused it to miss the spatial beamsplitter. Example of single frame images with different temporal offsets, collected within a single imaging session. Here, we showed an image for OCH1, which is fixed with images from OCH2 while setting different angles on mirror M3. Images are from the Indiana AOSLO. A: Reference image from OCH1, B: image from OCH2 displaced vertically by 36 µm in relation to OCH1, C: image displaced 65 µm vertically in relation to OCH1. The redline shows the location of a descending capillary (small round black feature in images).
