Laser Beam Schematic of Modified Micron Fundus Camera for LSCI. A xenon light source was replaced by a 10 mW 640 nm laser diode. A −6mm focal length (FL) plano-concave lens and 66.66 mm FL biconvex lens were added into the optical path to adjust the beam diameter. A pupil mask (PM) and linear polarizer (LP) were removed from the optical path, while a separate LP was introduced between the sample and the charge-coupled device (CCD). Other optical elements include a fold mirror (FM) and beam splitter (BS). Graphics used in this schematic were obtained from ComponentLibrary, a free graphics library by Alexander Franzen. Diagram not to scale.
