A Top view (y-z plane) of the setup. CL collimating lens, SPF short pass filter, LPF long pass filter, CYL achromatic cylindrical lens doublet, L achromatic lens doublet, M mirror, RM reference mirror, BS beamsplitter, GS galvo scanner, DCM dichroic mirror, FM flippable mirror, PH pinhole, DPSS diode-pumped solid-state laser, FIR-9 NKT FIR-9 OCT laser. The effective focal lengths: CL1 = 60 mm, CYL1 = CYL1R = CYL2 = L4 = L8 = 250 mm, L0 = 150 mm, L1 = L1H = L7 = 100 mm, L2 = CYL3 = 75 mm, L3 = L1R = L2R = L2H = L6 = 200 mm, CL2 = L5 = 30 mm. (I): conjugate image planes. (P): conjugate pupil planes. Not to scale. B Unfolded x-z view of the OCT illumination path showing line-field on the retina. C Optical paths for green (520 nm) and UV (385 nm) stimulation. DCM1-2 Dichroic mirrors 1 and 2, R retinal plane. The effective focal lengths: LG2 = 30 mm, LUV1 = 100 mm, LUV2 = 35 mm.
