a Set up for obtaining the spectral curve and power output of a light source. The spectrophotometer (white arrow) and power meter (yellow arrow) are linked to the integration sphere (black arrow). The light shining into the integration sphere generates a spectral curve captured by the spectrophotometer also linked to the computer software. The power obtained is directly shown by the power meter. b Spectral curve of a light source (blue curve), as a function of wavelength and intensity output, against an aphakic hazard curve (yellow) and a photopic eye response curve (purple)
